This talk serves \nto provide a detailed overvie w of the development of a Burn-in test station for an \nupgraded LVPS component known as a Brick. These Bricks are radiation ha rd \ntransformer-coupled buck converters that function to step-down bulk 200 V Direct \nCurrent (DC) power to the 10 V DC required by the on -detector electronics. To ensure \nthe high reliability of the Bricks\, on ce installed within the TileCal\, a burn-in test station \nhas been desi gned and built. The burn-in station functions to implement a bur n-in \nprocedure on eight Bricks simultaneously. This procedure subjec ts the Bricks to suboptimal operating conditions that function to accelerate their ageing as well as to \nstimulate failure mechani sms. This results in elements of the Brick that would fail \npre maturely within TileCal failing within the burn-in station or to experience \nperformance degradation that can be detected by follow-up te sting effectively screening \nout the non-performative sub-population. The burn-in station is of a fully custom design \nin both its hardware and so ftware. The development of the test station will be explored \nin detail\ , the preliminary burn-in procedure to be employed will be provi ded\, the \npreliminary and final commissioning of the test station will be presented culminating in \nan outlook of the project\n\nhttps://indico. tlabs.ac.za/event/112/contributions/3321/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/3321/ END:VEVENT BEGIN:VEVENT SUMMARY:Axion Detection: Techniques\, Experiments and Instrumentation DTSTART;VALUE=DATE-TIME:20230906T140000Z DTEND;VALUE=DATE-TIME:20230906T142000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3320@indico.tlabs.ac.za DESCRIPTION:Speakers: Ben McAllister (Swinburne University of Technology)\ nAxions are a hypothetical elementary particle originally proposed as a re sult of the Peccei-Quinn solution to the Strong CP problem. With the right masses\, axions are a compelling dark matter candidate and have been the subject of growing interest in recent years among the international dark m atter detection community. \n\nGenerally\, axion dark matter is very light – on the order of micro-eV in mass (give or take a few orders of magnit ude) meaning that detection techniques look radically different from commo n WIMP detectors. Axions are theorized to have several couplings to the st andard model\, the most probed of which is the axion-photon coupling. Ther e are various axion dark matter detection experiments around the world whi ch seek to exploit this coupling\, by converting axions into photons and v ice-versa.\n\nWe will discuss some of the common axion detection technique s\, with a focus on axion haloscopes\, and give an overview of some of spe cific experiments in the field such as ADMX and ORGAN. We will look at the current state of the art in axion detection and discuss the future of the field with a focus on instrumentation and detector technology.\n\nhttps:/ /indico.tlabs.ac.za/event/112/contributions/3320/ LOCATION: Meeting Room 2.61 - 2.63 URL:https://indico.tlabs.ac.za/event/112/contributions/3320/ END:VEVENT BEGIN:VEVENT SUMMARY:Design and Prototype Testing of the Homogeneous Crystal Calorimete r for STCF DTSTART;VALUE=DATE-TIME:20230905T160000Z DTEND;VALUE=DATE-TIME:20230905T162000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3323@indico.tlabs.ac.za DESCRIPTION:Speakers: Yong Song (University of Science and Technology of C hina)\nThe Super Tau-Charm Facility (STCF) is the next generation high lum inosity $e^{+}e^{-}$ collider focusing on the tau-charm physics. STCF will achieve a luminosity of over $0.5\\times10^{35} cm^{-2}s^{-1}$ at 4 GeV\, resulting in a high event rate and a high beam background for the detecto r system. The background count rate of over 1 MHz per module places new de mands on the electromagnetic calorimeter (EMC): maintaining good energy an d position resolution under severe pileup conditions. Meanwhile\, the deve lopment of event timing and particle identification capability is also an important aspect of calorimeter R&D\, where a time resolution of better th an hundreds of picoseconds is expected.\n\nThis talk summarizes the simula tion and optimization of the calorimeter system\, the prototype fabricatio n and the test results on the prototype are summarized. The STCF EMC is ba sed on a fast pure $CsI$ crystal and is read out by avalanche photodiodes (APD). By considering the effect of crystal and electronics response\, as well as the pileup condition\, a complete chain of simulation and reconstr uction is implemented in the Offline Software of Super Tau-Charm Facility (OSCAR). The architecture and module geometry of EMC are designed by optim izing the physical performance under OSCAR. Based on the module design\, a novel wavelength shifter (WLS)-enhanced prototype is fabricated\, which f eatures fast time response and good signal-to-noise ratio at a reasonable cost. The comprehensive test results on the prototype\, especially on the radiation hardness of the prototype\, the uniformity of the light collecti on and the cosmic ray-timing performance of the prototype\, are also prese nted.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/3323/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3323/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of Muon Tomography for the Geometry Validation of the CMS High Granularity Calorimeter DTSTART;VALUE=DATE-TIME:20230908T104000Z DTEND;VALUE=DATE-TIME:20230908T110000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3150@indico.tlabs.ac.za DESCRIPTION:Speakers: Indranil Das (CERN)\nThe high granularity calorimete r (HGCAL) of CMS is planned to operate during the high luminosity operatio n of the LHC\, replacing the existing electromagnetic and hadronic calorim eters at the endcap section.

HGTD\, based on Low Gain Avalanche Detector (LGAD) technology and covering the pseudor apidity region between 2.4 and 4.0\, will provide high precision timing in formation to distinguish between collisions occurring close in space but w ell-separated in time. Apart from being radiation resistant\, LGAD sensors should deliver 30 ps time resolution per track for a minimum-ionising par ticle (35 ps per hit) at the start of lifetime\, increasing to 50 ps per t rack (70 ps per hit) at the end of HL-LHC operation. Each readout cell has a transverse size of 1.3×1.3 mm2 leading to a highly granular detector w ith about 3 millions of readout electronics channels. A dedicated ASIC for the HGTD detector\, ALTIROC\, is being developed in several phases produc ing prototype versions of 2×2\, 5×5 and 15×15 channels. HGTD modules ar e hybrids of the LGAD and ALTIROC connected through flip-chip bump bonding process.Several test beam campaigns have been conducted at DESY and CERN SPS H6 beamline in 2022. The performance of irradiated Carbon-enriched LGA D sensors from different vendors has been studied.This talk covers the pro mising results in terms of collected charge\, time resolution and hit effi ciency of LGADs. A time resolution of < 70 ps is observed in most cases fo r highly irradiated sensors (2.5e15 neq/cm^2)\, while integrating timing i nformation to the EUDET system allows for a surface resolution of less tha n 50 μm. First module prototypes of 15×15 arrays with a pad size of 1.3 ×1.3 mm2 for the HGTD project have been tested from different manufacture rs. Their performance with charged particle beams before irradiation is ev aluated. A summary of the results from LGAD-only and hybrids will be pres ented.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/3286/ LOCATION: Auditorium 2 URL:https://indico.tlabs.ac.za/event/112/contributions/3286/ END:VEVENT BEGIN:VEVENT SUMMARY:The Upgrade of the Level-1 Muon Trigger at the CMS experiment for the High-Luminosity LHC era DTSTART;VALUE=DATE-TIME:20230904T161000Z DTEND;VALUE=DATE-TIME:20230904T163000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3237@indico.tlabs.ac.za DESCRIPTION:Speakers: Jacobo Konigsberg (University of Florida)\nWe presen t an innovative upgrade to the CMS Level-1 Muon trigger for the High Lumin osity LHC (HL-LHC) era.

In\nthis presentation\, we discuss detailed mea surements of the spatial and\nthe time structure of hadronic showers to ch aracterise the different\nstages of hadronic cascades in the calorimeters\ , which are then\nconfronted with GEANT4-based simulations using different hadronic\nphysics models. These studies also extend to the two different absorber\nmaterials\, steel and tungsten\, used in the prototypes. The hig h\ngranularity of the detectors is exploited in the reconstruction of\nhad ronic energy\, both in individual detectors and combined\nelectromagnetic and hadronic systems\, making use of software\ncompensation and semi-digit al energy reconstruction.

The T ile Calorimeter (TileCal)\, a sampling hadronic calorimeter covering the c entral region of the ATLAS experiment\, will require new electronics to me et the requirements of the High-Luminosity LHC (HL-LHC). This talk will de monstrate how deep neural networks can improve quality control of the new Low Voltage Power Supply (LVPS) boards in the contest of the ATLAS Phase-I I Upgrade program for HL-LHC. Deep Neural Networks (DNNs) as a machine lea rning algorithm is used to analyze complex data from the LVPS Boards. The first initial testing done on the boards determined their reliability and performance. A total of eleven tests with a binary metric of PASS/FAIL mak e up the initial test station. The measurements are stored in a database a nd the multi-dimensional data is explored and then analyzed by a DNN algor ithm. The DNN model classifies the data and produces significant insights with predictions about the quality of the LVPS boards. These forecasts wil l help the Quality Control of the upgraded TileCal LVPS.

These clusters ar e formed by aggregating neighbouring crystals according to the expected to pology of an electromagnetic shower in the ECAL.\n\nThe presence of upstre am material causes electrons and photons to start showering before reachin g the ECAL. This effect\, combined with the 3.8T CMS magnetic field\, lead s to energy being spread in several clusters around the primary one. It is essential to recover the energy contained in these satellite clusters to achieve the best possible energy resolution. Historically\, satellite clus ters have been associated to the primary cluster using a purely topologica l algorithm which does not attempt to remove spurious energy deposits from additional pileup interactions (PU). The performance of this algorithm is expected to degrade during LHC Run 3 (2022+) because of the larger averag e PU levels and the increasing levels of noise due to the ageing of the EC AL detector.\n\nNew methods are being investigated that exploit state-of-t he-art deep learning architectures like Graph Neural Networks (GNN) and se lf-attention algorithms. These more sophisticated models improve the energ y collection and are more resilient to PU and noise. This talk will cover the challenges of training the models and the opportunities offered by the deep learning techniques.\n\nhttps://indico.tlabs.ac.za/event/112/contrib utions/3176/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3176/ END:VEVENT BEGIN:VEVENT SUMMARY:Using NLP for Hardware Quality Control by predicting Alert Signals from Particle Accelerator Detectors DTSTART;VALUE=DATE-TIME:20230905T102000Z DTEND;VALUE=DATE-TIME:20230905T104000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3112@indico.tlabs.ac.za DESCRIPTION:Speakers: Nicholas Perikli ()\n*By Nicholas Perikli \nSchool o f Physics and Institute for Collider Particle Physics\, University of the Witwatersrand\, Johannesburg\, South Africa*\n\nAbstract.\nParticle physic s data consists of patterns in measurements that can be separated into hot topics and more mundane data. This approach is analogous to looking for k eywords or topics in huge text data by separating more specific words and phrases from the generalities of text through the application of NLP. This will be done using DCS alarm data. The NLP models that were constructed o r fine-tuned for text classification included SVM\, BERT- base-cased\, RoB ERTa-base\, as well as stacked LSTM and bi-LSTM. This was done on Google C olab using Pytorch and Python libraries\, and the hyperparameters were opt imised using the WandB platform\, in which an extensive Baye’s optimisat ion search was performed. The idea is to use the best-performing models i. e.\, BERT or RoBERTa and train them by fine-tuning their hyperparameters i n order to classify the alarms\, as well as predict future alarm signals\, and then follow the same procedure for an LSTM model and compare the resu lts. The inputs would contain information about the date and time the alar m was received\, the physical variable involved\, the type of error as wel l as the particular system\, component or sub- component affected. Since this data provides information about the detector components as well as th e abnormal values of the physical variables of their constituent parts dur ing a hardware malfunction\, as well as the length of time that is taken u ntil the issue is resolved\, this data can be used as a correlator for the status of other sub-detector components during a hardware malfunction of another component. Moreover\, the predictive power of this algorithm could avoid fatal errors in the functioning of the hardware and electronic syst ems especially during testing periods and upgrades and allow for faster an d more effective management and advancement of the hardware and electronic systems towards greater technological capabilities.\n\nhttps://indico.tla bs.ac.za/event/112/contributions/3112/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3112/ END:VEVENT BEGIN:VEVENT SUMMARY:Ultimate precision of a tracking system in future high energy expe riments DTSTART;VALUE=DATE-TIME:20230905T090000Z DTEND;VALUE=DATE-TIME:20230905T092000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2764@indico.tlabs.ac.za DESCRIPTION:Speakers: Gang LI (Institute of High Energy Physics\, Chinese Academy of Sciences)\nOne of the top goals of a high energy experiment is to perform precision tests on the Standard Model and probe new physics bey ond the Standard Model. Therefore\, it is essential to precisely measure t he momenta and impact parameters of charged tracks. Because of the rapid a dvancement of technology\, excellent tracking systems could be built. The most accurate silicon pixel tracker is approaching the spatial resolution of micron-level and a material budget of sub-permille-level. As a result\, the trade-off between spatial resolution and material budget becomes crit ical. Analytical calculation and fast simulation are used to examine the m aximum accuracy of a tracking system with restricted resolution and materi al budget.

An extruded plastic scintillator (EPS)-based active veto system for c osmic ray muons is being built around the existing miniICAL detector\, whi ch is a scaled-down version of the proposed ICAL detector\, at the transi t campus of India-based Neutrino Observatory in Madurai.\n\nIndividual det ector consists of extruded plastic scintillator (EPS) ($\\sim\\\,500cm \\t imes 5cm\\times 1cm$ ) consisting of two WLS fibres to collect scintillati on photons and four silicon-photomultipliers (SiPMs) as photo-transducers. Eight such detectors are grouped to form a module\, called a tile\, which is placed adjacent to other tiles to cover the entire mini-ICAL detector. To achieve high efficiency and cover the dead space\, up to four of these layers are stacked\, to form veto-wall. The CMV detector comprises four w alls\, one on top\, three on the sides\, making it an active veto system t hat covers the miniICAL detector. The performance of scintillators\, WLS f ibres\, SiPM readout systems\, and muon reconstruction in the miniICAL hav e been well established. Using these developments\, this work examines the feasibility of building such a large veto system around the miniICAL dete ctor using the GEANT4 toolkit. The efficiency of the CMV is estimated usin g reconstructed muon tracks in the RPC stack with sufficient hits and good fit quality. The performance of the CMV detector is tested with and witho ut a magnetic field using the muon reconstruction algorithm and extrapolat ing the same to the veto detector.\n\nThe goal is to achieve a veto effici ency $>$ $99.99\\%$ and a false-positive rate of less than $10^{-5}$. By a chieving this high level of veto efficiency\, the neutrino experiment can be conducted at a much shallower depth (just 100m) than what would normal ly be required (1.3km).

Thi s requires both assignment of energy deposits to particles and recovery of various properties across the detector. These tasks have traditionally be en performed by classical algorithms and BDT regressions\, both of which r ely on human-engineered high level quantities. However\, bypassing human f eature engineering and instead training deep learning algorithms on low-le vel signals has the potential to further recover lost information and impr ove the overall reconstruction. We have therefore developed novel algorith ms for particle reconstruction based on graph neural networks\, which allo w us to represent the energy deposits recorded in the calorimeter directly in our models. In this presentation we will show the performance of our G NN architecture applied to energy reconstruction in test beam data for the CMS High-Granularity Calorimeter (HGCAL)\, planned for operation in the H L-LHC\, which have shown an unprecedented improvement in the energy resolu tion of single hadrons compared to traditional rules based methods.

A nov el electromagnetic calorimeter (ECAL) with transverse crystal bars has bee n proposed for the future electron-positron collider experiments\, offerin g high intrinsic energy resolution\, 3D granularity required by the Partic le Flow Approach (PFA) and O(10) fewer readout channels. The main challeng es of this new design are the ambiguity problem for multiple simultaneousl y injected particles from the perpendicular arrangement of crystal bars an d the overlap between showers from larger Moliere radius of the crystal.\n \nIn this report we will present a new PFA with several sub-algorithms to address above issues\, and prove the feasibility of this ECAL design. The ambiguity problem is solved by multiple optimized pattern recognition app roaches\, and the overlapping showers are addressed by an energy splitting module. The global performance is preliminary investigated within the Cir cular Electron Positron Collider (CEPC) environment.

The ATLAS Monitored Drift Tub e (MDT) chambers are the main component of the precision tracking system i n the ATLAS muon spectrometer. It is important to understand any potential issues with the MDT Front-End (FE) readout electronics for an expected Le vel 1 (L1) trigger rate of 98 kHz and a complex dead time of over 4% for R UN3 operations. We use raw data collected in 2022 to emulate the expected hit rates in MDT chambers and perform a realistic simulation on the ATLAS Muon TDC (AMT) chip with the current configuration. We study the AMT chip performances by analyzing the trigger/L1/readout buffer occupancies and hi t-loss fractions under different luminosities with L1 rate of 100 kHz by u sing the Modelsim software. The hit-loss fraction of the hottest MDT chamb er (BIL3C05) is lower than 0.1% due to FE readout\, even at a luminosity o f 2.98 x1034 cm-2s-1 with a complex dead time of 5% and a L1 rate of 100 k Hz\, indicating that AMT can operate under Run 3 conditions without proble ms. The MDT trigger and readout electronics will be replaced for triggerle ss readout during High-Luminosity LHC (HL-LHC) operation. We also simulate the AMT behavior in the trigger-less mode up to 7x1034 cm-2s-1 and propos e possible AMT configurations in case some FE electronics could not be rep laced during the pre-HL-LHC shutdown.\n\nhttps://indico.tlabs.ac.za/event/ 112/contributions/2793/ LOCATION: Meeting Room 2.61 - 2.63 URL:https://indico.tlabs.ac.za/event/112/contributions/2793/ END:VEVENT BEGIN:VEVENT SUMMARY:The high-performance DIRC detector for ePIC Detector at the future Electron-Ion Collider DTSTART;VALUE=DATE-TIME:20230905T104000Z DTEND;VALUE=DATE-TIME:20230905T110000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3232@indico.tlabs.ac.za DESCRIPTION:Speakers: Greg Kalicy (CUA)\nThe next frontier project of nucl ear physics in the United States will be the Electron-Ion Collider (EIC)\, planned to be built in the Brookhaven National Laboratory (BNL).

The experiment will measure the spectra of electrons \, positrons and photons in expected ranges of $10^{−3}$ to $10^{9}$ per 1 Hz bunch crossing\, depending on the laser power and focus. These measu rements have to be performed in the presence of low-energy high radiation- background. To meet these challenges\, for high-rate electron and photon f luxes\, the experiment will use Cherenkov radiation detectors\, scintillat or screens\, sapphire sensors\, as well as lead-glass monitors for backsca ttering off the beam-dump. A four-layer silicon-pixel tracker and a compac t electromagnetic tungsten calorimeter will be used to measure the positro n spectra. The layout of the experiment and the expected performance under the harsh radiation conditions will be presented. Particular attention wi ll be devoted to the sapphire sensors gamma beam profiler (GBP) which shou ld provide a 5 um precise Compton-scattered gammas beam profile width\, wh ich in turn\, will allow a 5% determination of the absolute laser field in tensity experienced by the electron beam. This performances is quite chal lenging\, given the high irradiation dose experienced by the GBP (about 1 MGy/year). The use of sapphire sensors in high energy physics experiments is quite novel\, and details will be given on the R&D performed until now to assess their performances in the harsh environment of the LUXE experim ent. \nThe experiment has received stage 1 critical approval (CD1) from th e DESY management and is about to publish its technical design report (TDR ).

The whole silicon tracker (VX D) will be extracted from Belle II\, then the outer four-layer double-side d strip detector (SVD) is split into its two halves to allow access for th e PXD installation. Then a new VXD commissioning phase will begin such tha t it will be ready to take data by the end of 2023. We describe the challe nges and status of this VXD upgrade. \nIn addition\, we report on the perf ormance of the SVD\, which has been operated since 2019. The high hit effi ciency and the large signal-to-noise are monitored via online data-quality plots. \nThe good cluster-position resolution is estimated using the unbi ased residual with respect to the track\, resulting in reasonable agreemen t with the expectations. A novel procedure to group SVD hits event-by-even t\, based on their time\, has been developed. Using the grouping informati on during reconstruction allows to significantly reduce the fake rate whil e preserving the tracking efficiency. \nSo far\, in the layer closest to t he I.P.\, the SVD average occupancy has been less 0.5%\, which is well bel ow the estimated limit for acceptable tracking performance. As the luminos ity increases\, higher machine backgrounds are expected and the excellent hit-time information in SVD can be exploited for background rejection. We have developed a method that uses the SVD hit-time to estimate the collisi on time (event-T0) with similar precision to the estimate based on the dri ft chamber. The execution time needed to compute SVD event-T0 is three ord ers of magnitude smaller\, allowing a faster online reconstruction that is crucial in a high luminosity regime. Furthermore\, the front-end chip (AP V25) is operated in “multi-peak” mode\, which reads six samples. To re duce background occupancy\, trigger dead-time and data size\, a 3/6-mixed acquisition mode\, based on the timing precision of the trigger\, has been successfully tested in physics runs.\nFinally\, concerning the radiation damage\, the SVD dose is estimated by the correlation of the SVD occupancy with the dose measured by the diamonds of the monitoring and beam-abort s ystem. Although the sensor current and the strip noise have shown a modera te increase due to radiation\, we expect the detector performance will not be seriously degraded during the lifespan of the detector.\n\nhttps://ind ico.tlabs.ac.za/event/112/contributions/2978/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/2978/ END:VEVENT BEGIN:VEVENT SUMMARY:Spin Physics Detector at the NICA accelerator complex DTSTART;VALUE=DATE-TIME:20230905T140000Z DTEND;VALUE=DATE-TIME:20230905T142000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2962@indico.tlabs.ac.za DESCRIPTION:Speakers: Alexander Korzenev (Joint Institute for Nuclear Rese arch)\nThe Spin Physics Detector (SPD) is designed as a universal 4$\\pi$ detector with advanced tracking and particle identification for studying t he spin structure of the proton and deuteron and other spin-related phenom ena.

Ionization particles in liquid argon produce free charges and scint illation photons. Both signals are used to perform calorimetric measuremen ts\, particle identification and three dimensional reconstruction. LAr sci ntillation light can be quenched and absorbed by the presence of nitrogen contaminations. In neutrino detectors electronegative contaminants\, like oxygen and water\, are continuously filtered\, while nitrogen is not. Thi s can lead to a reduction of the scintillation signal in case of air leaks in the detector. Dark matter experiments typically filter nitrogen in gas phase at room temperature.\nA new innovative media for the purification o f argon from nitrogen in liquid phase will be presented. \nThe innovative molecular sieve is the zeolites Li-FAU. Purification tests have been perf ormed using the Liquid Argon (LAr) Purification Cryostat (PuLArC) at IFGW/ Unicamp. Previous studies performed with nitrogen gas at T=89 K\, revealed a strong interaction of nitrogen with the lithium cations present in the zeolite LiX. The tests performed in PuLArC have unequivocally shown that t he Li-FAU adsorbent is capable of capturing N2 recirculating argon in liqu id phase. The Li-FAU was able to reduce a N2 contamination of 20-50 ppm ( part per million) to 0.1-1.0 ppm in 1-2 hours of circulation time. The tes t was repeated several times. These results invoke further investigations in larger scale LAr cryostats at Fermilab and CERN in order to support the possible use of Li-FAU molecular sieve\, in replacement of Molecular Siev e 4A\, in LBNF-DUNE and other LAr experiments.\n\nhttps://indico.tlabs.ac. za/event/112/contributions/3121/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3121/ END:VEVENT BEGIN:VEVENT SUMMARY:Detector physics and event reconstruction at the MicroBooNE experi ment.

The liquid scintillator target is cont ained in an acrylic sphere with a diameter of 35.4 meter\, which is suppor ted by a stainless steel latticed shell structure outside. There are about 18\,000 20-inch photomultiplier tubes (PMTs) and 25\,000 3-inch PMTs faci ng inwards and installed at the inner surface of stainless steel structure with extremely high photon coverage. The detector is located in a water p ool which mitigates the natural radioactivity from the surrounding rocks. The onsite installation of the JUNO detector\, which is expected to face e normous challenges and difficulties due to the huge size and high requirem ent\, started in early 2022 after completing the civil construction. The s tainless steel structure had been almost finished except the bottom area\, which is also served as the transportation path during the acrylic vessel construction\, and 120\,000 sets of special bolts were used during assemb ly. Right after the construction of stainless steel structure\, the onsite installation of the acrylic vessel started from top to bottom\, which req uires 263 huge acrylic panels to be bulk-polymerized layer by layer. The P MTs installation follows the acrylic sphere construction. The detector wil l be filled 20 kton LS in the acrylic vessel and 3.5 kton ultra-pure water in the water pool next year.

A sterile neutrino with a mass up to 1 8.6 keV would manifest itself in the decay spectrum as a kink-like distort ion. The objective of the TRISTAN project is to extend the Karlsruhe Triti um Neutrino Experiment (KATRIN) with a novel multi-pixel silicon drift det ector and readout system to search for a keV-scale sterile neutrino signal .

The PHYDES project is an R&D experim ent funded by CSN V of INFN aimed to test innovative approaches for e-EDM studies.

In particular\, excitation transfer becomes important for fast sc intillation response.\nIn this work\, we adopted nonlinear optical spectro scopy to study the processes limiting the rate of excitation transfer in a ctivated scintillators\, especially in those with multicomponent crystalli ne matrix where the transfer might be affected by carrier trapping due to the potential fluctuations caused by compositional disorder. Transient opt ical absorption technique in pump and probe configuration was exploited to monitor the time evolution of nonequilibrium carrier density. Selective e xcitation using tuneable-wavelength pulses and measuring a wide spectrum o f transient absorption (TA) at variable delay after short pulse excitation enabled the identification of the type of nonequilibrium carriers respons ible for TA and revealing the peculiarities of excitation transfer. Time-r esolved photoluminescence was also exploited.\nOur study was focused on tw o families of prospective Ce-doped scintillators: lutetium yttrium oxyorth osilicates (LYSO:Ce) and gadolinium aluminium gallium garnets (GAGG:Ce). T he comparison of the TA response rise time with the coincidence time resol ution\, which is a conventional parameter measured under gamma excitation\ , showed that the delay in the front of the TA response due to the populat ion of the lowest (emitting) excited level of Ce3+ after excitation of the ion to higher excited levels reflects the electron transfer that is affec ted by electron trapping. The influence of aliovalent codoping on the lumi nescence response time was studied in LYSO:Ce\,Ca and GAGG:Ce\,Mg with dif ferent codoping level. It is shown that the codoping results in faster lum inescence response due to elimination of trapping centers and enhances the luminescence decay rate due to introduction of quenching centers. A trade -off between luminescence efficiency and decay time is considered.\n\nhttp s://indico.tlabs.ac.za/event/112/contributions/2783/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/2783/ END:VEVENT BEGIN:VEVENT SUMMARY:Understanding the temperature dependence of SiPM characteristics DTSTART;VALUE=DATE-TIME:20230907T142000Z DTEND;VALUE=DATE-TIME:20230907T144000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3219@indico.tlabs.ac.za DESCRIPTION:Speakers: Gobinda Majumder (Tata Institute of Fundamental Rese arch\, Mumbai\, India)\nThe prototype detector of the ICAL experiment at t he India-based Neutrino Observatory\, the mini-ICAL\n is in operation at the IICHEP\, Madurai.

Along with their advantages of having low operating voltages\, high PDE\, and excellent single-photon resolution\, t hey cause secondary photon emissions which are responsible for at least th ree processes: (i) internal cross-talk (ii) external cross-talk and (iii) optically-induced afterpulsing. While the internal crosstalk and afterpuls ing involves photon transport within the SiPM\, the external cross-talk ph otons escape from the surface of one SPAD and potentially: (i) reflect bac k into the SiPM at the surface coating interface and trigger avalanches in neighbouring SPADs\, (ii) transmit through the SiPM surface coating. Exte rnal crosstalk can be a significant background in future multi-ton detecto rs such as DarkSide-20k and nEXO that will cover large surface areas with SiPMs which can trigger each other in the vicinity. This may reduce the ac curacy of photo-electron resolution for high photo-electron events\, leadi ng to a degradation in the position and energy reconstruction. To quantify the systematic effects which deteriorate the overall performance of such detectors\, a study on SiPM secondary photon emission was conducted. It de termined the absolute secondary photon yield equal to the number of photon s emitted per charge carrier ($\\gamma/e^-$) using a spectroscopy setup at TRIUMF\, Canada. The setup comprises an Olympus IX83 microscope with ligh t filters and a Princeton Instruments spectrometer. The SiPM is triggered by 405 nm laser that stimulates the emission of secondary photons from the SiPM. These photons pass through the long pass filter of the microscope t o finally be detected by the spectrometer. We have characterised FBK VUV-H D3\, HPK-VUV4\, and the FBK NUV-HD Cryo SiPMs at 163 K and 87 K (for FBK N UV-HD Cryo) to mimic the SiPM performance at liquid Xenon and liquid Argon temperatures. In this talk\, I will summarise the data analysis used to q uantify the secondary photon yield at these temperatures.

When the irradiated SiPMs were subjected to temperature sensitivity testing from -30°C to 20°C\, it was noticed that in-situ current annealing corrected the decreased sensitivit y of SiPMs to temperature and enhanced the energy resolution of SiPMs\, wh ich restored the peak position of SiPMs to nearly 80% of their pre-irradia tion levels. In conclusion\, our outcomes demonstrate considerable enhance ment of SiPM properties following in-situ current annealing. Therefore\, o ur short-duration but higher-ampere in-situ annealing provides a practical and effective method to improve the radiation resistance of SiPMs in spac e and collider experiments.\n\nhttps://indico.tlabs.ac.za/event/112/contri butions/2994/ LOCATION: Auditorium 2 URL:https://indico.tlabs.ac.za/event/112/contributions/2994/ END:VEVENT BEGIN:VEVENT SUMMARY:Studies on wide dynamic-range SiPMs with high pixel densities DTSTART;VALUE=DATE-TIME:20230907T144000Z DTEND;VALUE=DATE-TIME:20230907T150000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2992@indico.tlabs.ac.za DESCRIPTION:Speakers: Zhiyu Zhao (TDLI/SJTU)\nThe future Circular Electron -Positron Collider (CEPC)\, as one of future large-scale scientific facili ties for high energy lepton collider experiments\, aims to accurately meas ure the Higgs boson\, electroweak physics and the top quark.

To cover a large energ y range of a crystal detector unit (typically on the order of magnitude fr om 100keV to 10GeV) would lead to a stringent requirement on the SiPM dyna mic range. Two promising SiPM candidates (from NDL and HPK) with a sensiti ve area of $3\\times3~mm^2$ and 6 micron and 10 micron pixel pitches respe ctively\, have been identified for detailed studies. A dedicated test-stan d has been developed to address the challenge of response calibration for the wide dynamic-range SiPMs in a typical range from single photon to the order of 100k photons.\nMeanwhile\, a Monte Carlo simulation model has bee n developed for a deeper understanding and comparisons with experimental m easurements. The SiPM simulation model includes SiPM's characteristics e.g . Photon Detection Efficiency (PDE)\, inter-pixel optical crosstalk\, afte r-pulse and pixel recovery time\, etc. \nIn this contribution\, the dedica ted setup for characterizations of the SiPM dynamic range will be firstly presented\, followed by the experimental measurements of SiPMs with high p ixel densities and comparisons with the simulation predictions.

SiPM optical readout offers a large set of advant ages being cheap devices\, highly efficient and insensitive to the high ma gnetic field (~ 1.5 T) at the expected location of the sensors in the expe riment. On the other hand\, SiPM are not radiation tolerant and despite th e integrated radiation level is expected to be moderate (< 10$^{11}$ 1-MeV n$_{\\rm eq}$/cm$^{2}$) it should be tested whether single-photon countin g capabilities and the increase in Dark Count Rate (DCR) can be kept under control over the years. Several options are available to maintain the DC R to an acceptable rate (below ~100 kHz/mm$^{2}$)\, namely by reducing the SiPM operating temperature and by recovering the radiation damage with hi gh-temperature annealing cycles. Moreover\, by utilising high-precision TD C electronics and selecting bunch crossing information\, the use of timing information can effectively reduce background due to DCR.\n\nIn this talk we present the current status of the research and the results on studies performed on significant samples of commercial and prototype SiPM sensors. The devices have undergone proton irradiation in two campaigns in 2021 an d 2022. The first campaign aimed at studying the device performance with i ncreasing NIEL doses up to 10$^{11}$ 1-MeV n$_{\\rm eq}$/cm$^{2}$ delivere d at once to different sensor subsets and after long high-temperature anne aling cycles to recover the radiation damage. The second campaign aimed at studying the reproducibility of the performance in repeated irradiation-a nnealing cycles\, where the sensors have undergone high-temperature anneal ing cycles to recover the radiation damage. During the second campaign it was also explored the use of Joule annealing as a potential way to perform high-temperature annealing in-situ. In October 2022 the sensors were moun ted inside the dRICH detector prototype and successfully tested with parti cle beams at the CERN PS accelerator. \n\nThe results reported here\, obta ined in laboratory with SiPM characterisation measurements and in test-bea m measurements\, are based on the first 32-channel prototypes of the ALCOR chip and on a complete readout system. ALCOR is an ASIC chip that offers both single photon counting and Time-over-Threshold modes with a time reso lution of 50 ps and an event rate capability of up to 5 MHz per channel\, originally designed for reading out silicon photomultipliers at low temper atures.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/2777/ LOCATION: Auditorium 2 URL:https://indico.tlabs.ac.za/event/112/contributions/2777/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of the interaction trigger system for study of nucleus – nucleus collisions at BM@N/NICA experiment DTSTART;VALUE=DATE-TIME:20230904T163000Z DTEND;VALUE=DATE-TIME:20230904T165000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2989@indico.tlabs.ac.za DESCRIPTION:Speakers: Sergey Sedykh (Joint Institute for Nuclear Research) \nThe fixed-target experiment “Baryonic Matter at Nuclotron” (BM@N) is aimed to study characteristics of hot and dense nuclear matter produced i n nucleus – nucleus collisions at beam energies of 2 – 4 A GeV.

In this approach the Earth’s atmosphere is used as a calorimeter prov iding EAS Cherenkov arrays high energy resolution. Another advantage of th e method is its high time resolution which results in a good angular resol ution.

So\, to calibrate such arrays is not simple task. We developed a calibration system of EAS Cherenkov arrays based on a single fast light source on board of remotely controlled commercial drone helicopter. The light source is based on a single high power blue InGaN L ED driven by avalanche transistors driver. The light source provides light pulses with 2-3 ns (FWHM) width and 1010-1011 photons per pulse. Prelimin ary results of test flights of the calibration system are presented.

TileCal\, the central h adronic calorimeter of the ATLAS experiment at the Large Hadron Collider ( LHC)\, is readout by about 10\,000 photomultipliers (PMTs). Earlier studie s of performance showed a degradation in PMT response as a function of the integrated anode charge. At the end of the High-Luminosity LHC (HL-LHC) p rogram\, the expected integrated charge for PMTs reading out the most expo sed cells is 600 C. A model of the evolution of the PMT response as a func tion of the integrated charge\, based on the measurement response during t he Run 2\, was built. The projected loss at the end of the HL-LHC is 25% f or 8% of the total TileCal PMTs. These PMTs will be replaced with a newer version\, in order to keep the global detector performance at an optimal l evel. A local test setup is being used in the Pisa laboratory to study the long term response of the new PMT model considered for replacement in the TileCal readout of most exposed calorimeter cells. Furthermore\, the perf ormance of the new is compared to the old PMT model\, the current version used to readout TileCal cells. For the first time this new PMT model has b een tested after integrating more than 800 C of anode charge. Preliminary results obtained from data collected in the Pisa laboratory over a period exceeding one year are shown in this presentation. We started a study aime d to understand the response degradation of the PMTs in order to disentang le the effect of loss of quantum efficiency and change in gain.\n\nhttps:/ /indico.tlabs.ac.za/event/112/contributions/3201/ LOCATION: Meeting Room 2.61 - 2.63 URL:https://indico.tlabs.ac.za/event/112/contributions/3201/ END:VEVENT BEGIN:VEVENT SUMMARY:Study of the radiation aging of materials with using of beam of th e fast neutrons at BINP SB RAS DTSTART;VALUE=DATE-TIME:20230906T094000Z DTEND;VALUE=DATE-TIME:20230906T100000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2778@indico.tlabs.ac.za DESCRIPTION:Speakers: Viktor Bobrovnikov (Budker Institute of Nuclear Phys ics\, SB RAS)\nThe BINP SB RAS\, in collaboration with Novosibirsk State U niversity\,has upgraded facility for boron-neutron capture therapy for the possibility of radiation tests on beam of fast neutrons with the integral flux up to 10^14 neq/cm2.\n\nIn 2022 the experiment on the study of the r adiation aging of optical fibers for the laser calibration system of elect romagnetic calorimeter CMS (CERN\, Switzerland) was carried out.

To demonstrate the time resolution\, we b uilt a prototype detector with a LaB6 photocathode. We successfully detect ed single-photon signals. We performed a waveform fitting to precisely mea sure the timing of the signals\, and measured the time resolution to be 25 ±0.2 ps at the gain of $3.3 \\times 10^{6}$. \nWe also studied the photo n feedback event that is additional avalanches caused by UV photons from t he primary avalanche. Because the photon feedback doubles or triples the o utput charge\, it was clearly seen in the charge distribution of the signa ls. We extracted the probability of the photon feedback by fitting the cha rge distribution. Using this result\, we determined the photon feedback pr obability to be 0.3 under assumption of a Poisson model. Photon feedback p robability can be larger with a photocathode that has a better quantum eff iciency\, and it can be a major challenge in practical application of the gaseous photodetectors. \nIn this presentation\, we will discuss the detai ls of the above measurements and prospects of the future R&D of this photo detector.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/3227/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3227/ END:VEVENT BEGIN:VEVENT SUMMARY:A square PMT module with 256 channels of <100 ps timing accuracy DTSTART;VALUE=DATE-TIME:20230904T161000Z DTEND;VALUE=DATE-TIME:20230904T163000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3105@indico.tlabs.ac.za DESCRIPTION:Speakers: James Milnes (Photek Ltd)\nPhotek have developed a s quare microchannel plate (MCP) PMT using 6 µm pore MCPs to achieve superi or timing\, compared to the previous generation which used 15 µm pores.

Usi ng precise time-difference measurement\, the position can be obtained more precisely than the conventional x-y strip readout with the same number of electronics channels. This technique was reported in the case of multigap RPCs (MRPCs) in [1] with timing difference resolution of 18 ps correspond ing to position resolution of 1.7 mm\, with sensitivity of 104ps/cm. The s ensitivity is defined as the ratio of the change in mean of timing-differe nce to the change in position where the particle crosses the gas gap. Sens itivity is just twice the inverse of propagation speed in the transmissio n line formed by the pickup strips. In [1]\, the readout strips on either side of the MRPC are kept in parallel\, and the signals from both ends of the strip are read differentially to minimise noise. It is expected that t his method would work on single-gap RPCs also as the signal will be induce d to both sides of a strip simultaneously. The intrinsic fluctuations of t iming of the device is common to both ends of the strip and gets cancelled out when the timing-difference is taken (pulse height effect may bias the time measurements). However\, MRPCs which are operated at higher electric fields produce a sharper rising signal than the single-gap RPCs\, so the position resolution may not be as good for single-gap RPCs as in the case of MRPCs. A similar method has been tested on single-gap RPCs in [2] achie ving a position resolution of 10.69 mm (timing difference resolution of 15 0 ps)\, but this was done using single-ended signals with pickup strips mo unted only on one side of the RPC. Single-ended readout will limit the tim ing-difference resolution as compared to differential readout. A similar m ethod has been tested in the development of the Improved RPCs (iRPCs) in C MS [3] with a resolution of 16mm (160 ps timing-difference resolution)\, a nd in [4] with a resolution of 5mm. This work will present the development of readout electronics for differential readout of RPCs and the measureme nt of the timing-difference resolution and sensitivity of the RPC using a cosmic muon telescope.\n\n[1] MRPC-PET: A new technique for high precision time and position measurements K.Doroud et al\, Nuclear Instruments and M ethods in Physics Research A (2011) https://doi.org/10.1016/j.nima.2011.09 .008 \n\n[2] Studies on fast triggering and high precision tracking with R esistive Plate Chambers G.

The tendency is to leave the ha rdware trigger system in favour of a complete or partial acquisition of th e front-end data paired with a powerful online software event discriminati on. Hardware trigger systems usually have to deal with a tight latency bud get due to the narrow readout buffering. To reduce the selection inefficie ncies resulting from the adoption of not optimal trigger algorithms due to the limited time budget and online computing resources\, the main trigger schema is going to be revisited. The traditional first trigger level is g oing to be replaced by a hardware pre-processing of the data stream follow ed by a software online selection [1\,2\,3].\nIn a DAQ system a large frac tion of CPU resources is engaged in networking rather than in data process ing. The common network stacks that take care of network traffic usually m anipulate data through several copies performing expensive operations. Thu s\, when the CPU is asked to handle networking\, the main drawbacks are th roughput reduction and latency increase due to the overhead added to the d ata transmission process. Networking with zero-copy can be achieved by add ing a RDMA layer to the network stack and making dedicated hardware take c are of the burden of the stack handling.\nThe main goal of the RDMA implem entation in the detector front-end electronics is to move up the adoption of clever networking protocols to the data producer. Therefore\, it is the front-end electronics that could take care of initiating the RDMA transfe r towards the computing farm. In such a way it is possible to eliminate th e point-to-point connection between the front-end and the back-end leaving the freedom of switching dynamically the routing to the computing nodes a ccording to their processing availability. By appropriately choosing the n etwork protocol for RDMA it is also possible to obtain a two-fold benefit. The possibility of adopting commodity hardware makes the DAQ system reduc e reliance on custom hardware and it exploits all the advantages of a matu re technology. In this way\, the DAQ system gains in scalability and easin ess of maintainability.\nRoCE is the natural choice as it is the only indu stry-standard Ethernet-based RDMA solution with a multi-vendor ecosystem. In this work the main firmware block needed for the realisation of the RoC E endpoint has been implemented and verified. A real-time firmware simulat ion of the RoCE network stack has been developed where real network packet s are exchanged between free-running Systemverilog code and the host machi ne via a TUN/TAP device which emulates a connection with a physical device (FPGA). The second part is devoted to show the verification process of th e modified RoCE stack using the tools developed so far such as the novel s imulation framework. The lightweight RoCE will be a stripped down version of the already verified firmware allowing the deployment on FPGAs with a l ow resource pool possible target devices could be rad-hard FPGAs used in f ront-end detector boards.\n[1] LHCb Collaboration\, LHCb Trigger and Onlin e Upgrade Technical Design Report\, CERN-LHCC-2014-016\, LHCB-TDR-016\n[2] CMS Collaboration\, The Phase-2 Upgrade of the CMS Data Acquisition and H igh Level Trigger Technical Design Report\, CERN-LHCC-2021-007\, CMS-TDR-0 22\n[3] Ryu\, FELIX: The new detector readout system for the ATLAS experim ent\, JINST Volume 898\, 2017\n\nhttps://indico.tlabs.ac.za/event/112/cont ributions/2951/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/2951/ END:VEVENT BEGIN:VEVENT SUMMARY:Drift chamber with cluster counting techniques for CEPC DTSTART;VALUE=DATE-TIME:20230907T150000Z DTEND;VALUE=DATE-TIME:20230907T152000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3259@indico.tlabs.ac.za DESCRIPTION:Speakers: Guang Zhao ()\, Shuaiyi Liu (Institute of High Energ y Physics)\nThe Circular Electron Positron Collider (CEPC) is designed to operate at center-of-mass energies of 240 GeV as a Higgs factory\, as well as at the Z-pole and the WW production threshold for electroweak precisio n measurements and study of flavor physics. A good identification of charg ed kaons is essential for the flavor physics and benefits the determinatio n of jet flavor and jet charge. To achieve these physics goals\, a design of tracking system combining a silicon tracker and a drift chamber is prop osed. The silicon tracker provides excellent spatial resolution and granul arity to cope with track separation in dense jets. The drift chamber could provide excellent particle identification (PID) performance with cluster counting technique. The cluster counting\, which measures the number of pr imary ionizations (dN/dx) instead of the energy loss (dE/dx) along the par ticle trajectory in a gaseous detector\, represents the most promising bre akthrough in PID. The Poissonian nature of the dN/dx offers a more statist ically significant way of ionization measurement\, which makes the dN/dx p otentially has a resolution two times better than the dE/dx. \nIn this pre sentation\, detailed PID study of the CEPC drift chamber will be discussed . Simulations from the ideal model to a more realistic one have been carri ed out. The ideal model\, which only simulates the ionization process with out considering the detector response\, shows promising PID performance fo r dN/dx over dE/dx. The realistic model\, which includes the detector and electronics responses as well as the reconstruction algorithm\, is used to optimize the drift chamber design and to provide the PID performance. A p reliminary CEPC drift chamber design is proposed. The PID performance in t erms of the kaon and pion separation power with one meter track for 20 GeV /c momentum can reach 2σ level\, which satisfies the preliminary physics requirements of CEPC.\n\nhttps://indico.tlabs.ac.za/event/112/contribution s/3259/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3259/ END:VEVENT BEGIN:VEVENT SUMMARY:A project to develop a few kt GAGG(Ce) scintillator detector for l ow energy neutrino studies at the Baksan Neutrino Observatory DTSTART;VALUE=DATE-TIME:20230907T154000Z DTEND;VALUE=DATE-TIME:20230907T160000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3155@indico.tlabs.ac.za DESCRIPTION:Speakers: Sultim Lubsandorzhiev ()\nWe present a project to de velop Gallium containing scintillator detector for low energy neutrino stu dies.

The detector will be located at the depth of 4700 m.w.e. (meter of water equivalent). A target mass of the detector wi ll be 10 kt. This multipurpose detector is being developed to study primar ily natural neutrino and antineutrino fluxes namely fluxes of solar neutri nos\, geoneutrinos and neutrinos from other astrophysical sources. The pro ject is aimed to have a record energy resolution which along with its loca tion at the large depth and relatively far distance from operating nuclear reactors will allow reaching a record sensitivity to the natural neutrino and antineutrino fluxes.

Monolithic active pixel sensors (MAPS) produced using commercial CMOS imaging processes are attractive in a particle physics co ntext\, as they allow for a reduced material budget and reduction of produ ction complexity and cost compared to hybrid sensors. The use of commercia l processes enables relatively cheap large-scale production of sensors\, b ut it also means that precise information of the doping concentrations and manufacturing process may not be publicly available. Exact predictions of sensor behaviour are thus difficult to make\, as the detailed electric fi eld configuration in the sensitive material is highly dependent on the ext ent and concentration of different doping regions in the silicon.\nThis ta lk aims to demonstrate that by making basic assumptions and performing sim ulations based on the fundamental principles of silicon detectors and usin g generic doping profiles\, performance parameters of MAPS can be inferred and compared for different sensor geometries. A procedure for this will b e described in detail\, along with example results. The described procedur e utilises Sentaurus TCAD and Allpix Squared\, and serves as a toolbox for performing sensor response simulations without detailed knowledge of the sensor doping concentrations and manufacturing process.\n\nhttps://indico .tlabs.ac.za/event/112/contributions/3224/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3224/ END:VEVENT BEGIN:VEVENT SUMMARY:Novel pixel sensors for the Inner Tracker upgrade of the ATLAS exp eriment DTSTART;VALUE=DATE-TIME:20230907T104000Z DTEND;VALUE=DATE-TIME:20230907T110000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3146@indico.tlabs.ac.za DESCRIPTION:Speakers: Stefano Terzo (IFAE\, Bracelona)\nThe High Luminosit y upgrade of the Large Hadron Collider at CERN\, the HL-LHC\, is expected to provide up to 200 proton-proton interaction per bunch crossing deliveri ng about 4000 fb$^{-1}$ of data over 10 years.\nTo operate in such a harsh particle environment the present inner detector of ATLAS experiment will be replaced by a completely new Inner Tracker (ITk).

SiC features multiple advantageous material properties over silicon. It is insensitive to visible light\, hypothesized to be more radiation ha rd\, and has much lower leakage currents\, even after irradiation. Especia lly for future high-luminosity experiments\, the radiation hardness is an essential parameter. One of the most important metrics associated with rad iation hardness is the charge collection efficiency (CCE)\, which typicall y decreases with irradiation due to the formation of traps and defects. A thorough understanding of these traps and defects is crucial for estimatin g the performance of a detector over its lifetime and can open to the door to techniques such as defect engineering.\nWe present the current status of characterization and simulations for 50 μm thick 4H SiC PiN diodes tog ether with radiation hardness studies. The characterization work includes the determination of material parameters of 4H-SiC (ionization energy and Fano factor) and comparisons to TCAD and Monte-Carlo simulations. Recently \, significantly increased signals (with respect to unirradiated samples) were reported for neutron-irradiated SiC diodes in forward bias using UV-T PA-TCT\, hinting at charge multiplication. We re-investigate neutron irrad iated 4H-SiC PiN diodes (fluences between $5\\times 10^{14}$ and $1 \\time s 10^{16}$ cm$^{-2}$ 1 MeV neutron equivalent $n_{\\text{eq}}$) which have been previously characterized using UV-TCT and alpha spectroscopic measur ements. The CCE and transient waveforms were measured in forward and rever se bias using alpha and UV-TCT measurements. Furthermore\, I-V and C-V mea surements for forward as well as reverse bias voltages of up to 3kV were p erformed to serve as additional input in understanding observed radiation damage. For samples irradiated to $5\\times 10^{14}$ and $5\\times 10^{14 }$ $n_{\\text{eq}}$ cm$^{-2}$\, the CCE in the forward direction grows ex ponentially\, surpassing 100% and coinciding with an increase in the leaka ge current. At the highest irradiation fluence\, no exponential behavior w as observed. However\, the CCE in the forward direction was found to be la rger than for reverse bias. For this fluence\, the leakage current remaine d below 1 nA.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/2899/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/2899/ END:VEVENT BEGIN:VEVENT SUMMARY:The Phase-II Upgrade of the ATLAS Hadronic Tile Calorimeter for th e High Luminosity LHC DTSTART;VALUE=DATE-TIME:20230907T144000Z DTEND;VALUE=DATE-TIME:20230907T150000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3225@indico.tlabs.ac.za DESCRIPTION:Speakers: Edward Nkadimeng (University of the Witwatersrand)\n Abstract. The Tile Calorimeter (TileCal) is a sampling hadronic calorimete r covering the central region of the ATLAS experiment\, with steel as abso rber and plastic scintillators as active medium. The High-Luminosity phase of LHC\, delivering five times the LHC nominal instantaneous luminosity\, is expected to begin in 2029. TileCal will require new electronics to mee t the requirements of a 1 MHz trigger\, higher ambient radiation\, and to ensure better performance under high pile-up conditions. Both the on- and off-detector TileCal electronics will be replaced during the shutdown of 2 026-2028. PMT signals from every TileCal cell will be digitized and sent d irectly to the back-end electronics\, where the signals are reconstructed\ , stored\, and sent to the first level of trigger at a rate of 40 MHz. Thi s will provide better precision of the calorimeter signals used by the tri gger system and will allow the development of more complex trigger algorit hms. The modular front-end electronics feature radiation- tolerant commerc ial off-the-shelf components and redundant design to minimize single point s of failure. The timing\, control and communication interface with the of f-detector electronics is implemented with modern Field Programmable Gate Arrays (FPGAs) and high speed fibre optic links running up to 9.6 Gb/s. Th e TileCal upgrade program has included extensive RD and test beam studies. A Demonstrator module with reverse compatibility with the existing system was inserted in ATLAS in August 2019 for testing in actual detector condi tions. The ongoing developments for on- and off-detector systems\, togethe r with expected performance characteristics and results of test-beam campa igns with the electronics prototypes will be discussed.\n\nhttps://indico. tlabs.ac.za/event/112/contributions/3225/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/3225/ END:VEVENT BEGIN:VEVENT SUMMARY:The upgrade of the CMS Muon System for the LHC Phase 2 DTSTART;VALUE=DATE-TIME:20230907T152000Z DTEND;VALUE=DATE-TIME:20230907T154000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2897@indico.tlabs.ac.za DESCRIPTION:Speakers: Gabriella Pugliese ()\nDuring the Phase 2\, the Larg e Hadron Collider (LHC) will increase the instantaneous luminosity to 5-7. 5 x 10^34 cm-2 s-1\, representing a new challenge for the Muon System of t he CMS detector.

The comparison of LUCID luminosity measurements in different detector operating condition s to those obtained by the Tile Calorimeter and the Inner detector is used to measure and study the dominant systematic uncertainty associated with the LUCID luminosity measurements. There are several factors affecting lum inosity measurements\, these include the aging of photomultiplier tubes an d aging of scintillating tiles.

ATL AS TileCal is an experimental\ntool used in particle physics for measuring the energy of particles. The TileCal DCS\ncontinuously monitors all the h ardware and infrastructure for each subsystem. The Tile-in-\nOne (TiO) too l is used to visualize and analyze this temperature study. The TiO is a co llection\nof small\, independent web tools called plugins. Plugins assess the quality of data and\nconditions for ATLAS TileCal. A change in tempera ture inside the drawers alters the\nphotomultiplier tube (PMT) gain\, resu lting in readout electronics that give null results or data\nwith lots of errors. Implying that those results may not be used for physics data. The TileCal\ndrawers are water-cooled using a circuit below atmospheric pressu re to prevent leaks\,\nmaintain stable temperatures\, maintain constant PM T gain\, and finally\, maintain the stability\nof the electronics. A compa rative analysis is done to determine the development of the leaks\nor impr ovements achieved in the cooling system and the stable values of the tempe rature in\nthe drawers. The work aims to continuously study the variation of temperature in the module\nover a short period of time using the TiO pl atform and display it to a user in a friendly and\nintuitive manner using contemporary web technologies. The DCS provides temperature data\nthrough a dedicated interface called the DCS Data Viewer (DDV).

E xcellent energy resolution is crucial for studies of Higgs boson decays wi th electromagnetic particles in the final state\, as well as searches for very high mass resonances decaying to energetic photons or electrons. The CMS electromagnetic calorimeter (ECAL) is a fundamental component of these analyses\, and its energy resolution is crucial for the Higgs boson mass measurement. It also provides a measurement of the electromagnetic compone nt of jets\, and contributes to the measurement of calorimeter energy sums \, both of which are important for a wide range of CMS physics analyses.\n \nThe energy and timing response of the ECAL has been precisely calibrated exploiting the full Run 2 (2015-18) dataset\, and has been used for the l egacy reprocessing of these data. A dedicated calibration of each detector channel has been performed. This talk will summarize the calibration tech niques\, the improved ECAL performance that has been achieved\, and will d escribe how this impacts on the sensitivity of the Higgs mass measurement in the H->ZZ->4l and H->gg channels.\n\nThe calibration plans that are bei ng developed to maintain the optimum ECAL performance during LHC Run 3 (20 22-25) will also be discussed\, and results from the first year of operati on in 2022 will be shown. A new system has been developed to automatically execute the calibration workflows during data taking in Run 3. This new d evelopment aims to reduce the time needed to provide the best possible per formance for physics analyses by one order of magnitude\, and the status\, plans\, and operational experience with this system will be described.\n\ nhttps://indico.tlabs.ac.za/event/112/contributions/3216/ LOCATION: Auditorium 2 URL:https://indico.tlabs.ac.za/event/112/contributions/3216/ END:VEVENT BEGIN:VEVENT SUMMARY:The new readout system for the Alice Zero Degree Calorimeters in L HC Run 3 DTSTART;VALUE=DATE-TIME:20230905T142000Z DTEND;VALUE=DATE-TIME:20230905T144000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2902@indico.tlabs.ac.za DESCRIPTION:Speakers: Stefan Cristi Zugravel (INFN sezione Torino / Polite cnico di Torino)\nThe Zero Degree Calorimeters (ZDC) were designed to prov ide the measurement of the event geometry and luminosity in heavy-ion oper ation.\nIn order to exploit the potential offered by the LHC increased lum inosity in Run 3 the ZDC upgraded its readout system to be able to acquire all collisions in self-triggered mode without dead time.\nThe purpose of the upgrade was to enable the detector to cope with the increased event ra te\, while preserving its time and charge resolution performance.\nThe ZDC operating conditions in Run 3 Pb-Pb collisions are extremely challenging due to the presence of ElectroMagnetic Dissociation processes (EMD).\nWhen running in self-triggered mode the ZDC system will need to sustain a read out rate of ~ 2.5 MHz for the channels of the most exposed calorimeters th at compares to the foreseen hadronic rate of 50 kHz sustained by the other detectors.\nThe previous electronics\, based on Charge-to-Digital Convert ers (QDCs)\, with a fixed dead time of ~ 10 us\, and on readout through VM E bus\, could not cope with such a high rate.\nMoreover\, a crucial aspect of the ZDC operation in Run 3 is acquiring the events with a reduced bunc h spacing of 50 ns (lower than the length of the signal of ~ 60 ns) in the presence of a large signal dynamics (from a single neutron to ~ 60 neutro ns).\nThe new acquisition chain is based on a commercial 12 bit digitizer with a sampling rate of about 1 GSps\, assembled on an FPGA Mezzanine Card .\nThe signals produced by the ZDC channels are digitized\, and samples ar e processed through an FPGA that\, thanks to a custom trigger algorithm\, flags for readout the relevant portion of the waveform and extracts inform ation such as timing\, baseline average estimation and luminosity.\nThe ar chitecture of the new readout system\, the auto trigger strategy\, the fir mware structure and the ZDC performance during the 2022 Pb-Pb collisions a re presented.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/2902/ LOCATION: Auditorium 2 URL:https://indico.tlabs.ac.za/event/112/contributions/2902/ END:VEVENT BEGIN:VEVENT SUMMARY:ATLAS LAr Calorimeter Commissioning for LHC Run-3 DTSTART;VALUE=DATE-TIME:20230905T140000Z DTEND;VALUE=DATE-TIME:20230905T142000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3195@indico.tlabs.ac.za DESCRIPTION:Speakers: Yi-Lin Yang (Dallas SMU)\nTo cope with the increase of the LHC instantaneous luminosity\, new\n trigger readout electronics were installed on the ATLAS Liquid Argon\n Calorimeters.\n\n On the de tector\, 124 new electronic boards digitise at high speed 10\n times mor e signals than the legacy system.

The innermost layer will be placed at only 18 mm of radial distance from the interaction point guaranteeing at the same time a material budget as low as 0.05% of a radiation length X0.\n\nThe R&D on the sensor ASICs involves a series of submissions in silicon and the first one (named MLR1: Multi-Layer per Reticle 1) was completed at the end of 2 020. MLR1 provided several test structures containing transistors\, memori es and small matrices of pixels with integration of front-end electronics inside the sensitive area of the pixels\; these devices have been used to qualify the technology in terms of performance and radiation hardness. In particular\, to evaluate the charged particle detection performance\, this first submission includes 3 variants of pixel matrices: analog pixel test structure (APTS\, 4x4 pixels of 10\, 15\, 20 and 25 µm pitch\, with anal og readout)\; digital pixel test structure (DPTS\, 32x32 pixels of 15 µm pitch\, with digital in-pixel discrimination and digital readout)\; CE65 ( 64x32 pixels of 15 µm pitch\, test structures with rolling shutter analog readout).\n\nThis contribution will provide an overview of these test str uctures\, describing the results of characterisations performed with radio active sources and beam tests in order to choose the best pixel pitch and sensor configuration\, optimising timing\, charge collection efficiency an d stability after radiation damage.

At the ATLAS Phase-II Upgrade\, the particle densities and radiation levels will exceed current levels by a factor of ten. The instantaneous luminosit y is expected to reach unprecedented values\, resulting in up to 200 proto n-proton interactions in a typical bunch crossing. The new detectors must be faster and they need to be more highly segmented. The sensors used also need to be far more resistant to radiation\, and they require much greate r power delivery to the front-end systems. At the same time\, they cannot introduce excess material which could undermine tracking performance. For those reasons\, the inner tracker of the ATLAS detector was redesigned and will be rebuilt completely.\n\nThe ATLAS Upgrade Inner Tracker (ITk) cons ists of several layers of silicon particle detectors. The innermost layers will be composed of silicon pixel sensors\, and the outer layers will con sist of silicon microstrip sensors. This contribution focuses on the strip region of the ITk. The central part of the strip tracker (barrel) will be composed of rectangular short (~ 2.5 cm) and long (~5 cm) strip sensors. The forward regions of the strip tracker (end-caps) consist of six disks p er side\, with trapezoidal shaped sensors of various lengths and strip pit ches.

The content of these isotopes can be at the level of $10^{-15}$ of the total element c ontent. The Accelerator Mass Spectrometer developed by Budker Institute of Nuclear Physics (BINP AMS) successfully measures the concentration of 14C relative 12C. However\, there is a problem of separating the 10B isobaric background from 10Be. Beryllium-10 is used to date geological objects on a time scale from 1 thousand years to 10 million years.\nTo solve this pro blem we have proposed a new technique for ion identification based on meas uring both ion track ranges and ion energies in a low-pressure Time-Projec tion Chamber (TPC) with Gas Electron Multiplier (GEM) readout. We have dev eloped the TPC with a dedicated thin silicon nitride window for an efficie nt passage of ions. To begin with\, the characteristic of the low-pressure TPC were studied in isobutane at a pressure of 50 torr using alpha partic le sources. \nIn this work\, we set up the low-pressure TPC on BINP AMS fa cility and successfully measured track ranges and energies of ions from sa mples containing 14C. At the next stage\, we are going to carry out measur ements with samples containing 10Be. However\, using the obtained results and SRIM simulation we have already shown that the isobaric boron and bery llium ions can be separated by more than 10 sigma. This technique is propo sed to be applied in AMS for dating geological objects\, namely for geochr onology of Cenozoic era.\n\nhttps://indico.tlabs.ac.za/event/112/contribut ions/3215/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3215/ END:VEVENT BEGIN:VEVENT SUMMARY:Status and prospects of the low radioactivity Argon for dark matte r searches DTSTART;VALUE=DATE-TIME:20230906T142000Z DTEND;VALUE=DATE-TIME:20230906T144000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2900@indico.tlabs.ac.za DESCRIPTION:Speakers: Roberto Santorelli (CIEMAT - Madrid)\nA major global effort is currently underway to obtain radiopure argon for DarkSide-20k ( DS-20k)\, the first large-scale detector of the Global Argon Dark Matter C ollaboration (GADMC).

The scann er has an axial field-of-view (AFOV) of 200 cm and consists of 9 double-si ded concentric rings of SiPM panels. The addition of Xenon doping to the L Ar scintillator suppresses the long-lifetime component of the scintillatio n light\, allowing for higher data rates and potentially higher patient do ses\, if needed for a specific application. This is due to the faster de-e xcitation process in the LAr-Xenon mixture\, which allows for direct energ y transfer and emission of Xenon light\, compared to traditional fluoresce nce processes involving wavelength shifters (WLS). Moreover\, studies have shown that lowering the operating temperature of SiPMs to match the tempe rature of LAr significantly reduces the dark count rate within the SiPM.\n \nThe 3DΠ scanner project is a medical imaging application of the ongoing research and development efforts of the DarkSide collaboration\, which is focused on direct dark matter particle searches using LAr targets. The 3D Π monte carlo simulation package has been derived from the DarkSide simul ation package\, which is based on the Geant4 toolkit. The main objective o f our study was to evaluate the performance of the 3DΠ scanner using esta blished NEMA NU 2–2018 standards for spatial resolution\, sensitivity\, image quality\, count rate performance\, and timing resolution.\n\nThe sen sitivity of the 3DΠ scanner was measured to be 564.02 kcps/MBq at the cen ter of the scanner. The noise-equivalent count rates (NECRs) were found to be 1.5 Mcps at a concentration of 5.3 kBq/mL\, and increased to 3 Mcps at a concentration of 21.2 kBq/mL. The TOF resolution was measured as 160 ps . These preliminary results indicate that the system performance of the 3D Π scanner is comparable to\, if not better than\, other commercial scanne rs.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/3212/ LOCATION: Meeting Room 2.64 - 2.66 URL:https://indico.tlabs.ac.za/event/112/contributions/3212/ END:VEVENT BEGIN:VEVENT SUMMARY:Glass Scintillator HCAL at future e+e− Higgs factory DTSTART;VALUE=DATE-TIME:20230907T154000Z DTEND;VALUE=DATE-TIME:20230907T160000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2768@indico.tlabs.ac.za DESCRIPTION:Speakers: sen Qian (IHEP\,CAS)\nThe future e+e− Higgs factor y\, whose main goal is to achieve a precise measurement of mass and proper ties of the Higgs boson\, is the main development trend of the next-genera tion large collider. A big challenge for this goal is to fulfill an unprec edented jet energy resolution\, and the scheme selection of hadronic calor imeter (HCAL) is one of the most important factors. Scintillation material s can convert high-energy rays into visible light. Generally\, solid scint illator can be divided into crystal scintillator\, plastic scintillator\, glass scintillator and ceramic scintillator. Compared with crystal scintil lator\, the glass scintillator has many advantages\, such as a simple prep aration process\, low cost and continuously adjustable components. Therefo re\, glass scintillator has long been conceived for application in the nuc lear detection such as hadronic calorimeter. Given the deficiency of the c rystal and the plastic scintillator\, a new concept\, Glass Scintillator H adronic Calorimeter for CEPC (GS-HCAL)\, was proposed. In 2021\, the resea rchers in the Institute of High Energy Physics (IHEP) have set up the Larg e Area Glass Scintillator Collaboration (GS group) to study the new glass scintillator with high density and high light yield. Currently\, a series of high density and high light yield scintillation glasses have been succe ssfully developed. The GSHCAL conceptual design with preliminary detector optimization by simulation has been done. The physics potential and the R& D of the GSHCAL will be presented in this paper.\n\nhttps://indico.tlabs.a c.za/event/112/contributions/2768/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2768/ END:VEVENT BEGIN:VEVENT SUMMARY:The ALICE Inner Tracking System Upgrade DTSTART;VALUE=DATE-TIME:20230906T092000Z DTEND;VALUE=DATE-TIME:20230906T094000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2955@indico.tlabs.ac.za DESCRIPTION:Speakers: Valerio Sarritzu (CERN)\nThe ALICE experiment at CER N is developing an upgrade of the three innermost layers of the Inner Trac king System (ITS3) vertexing detector\, to be installed during the Long Sh utdown 3 of the LHC (2026-28)[1]. It will consist of three truly cylindric al sensors wrapped around the beam pipe\, a concept that is enabled by the flexible nature of silicon when thinned down to less than 50 µm[2]. The three layers will be installed at a distance of 30\, 24\, and 18 mm from t he interaction point\, respectively — so close that a thinner beam pipe will also be installed. Full tracker half-layers will be covered by single wafer-scale CMOS monolithic active pixel bent detectors measuring up to $ ~10 \\times 26$ cm$^2$ in size\, manufactured in a commercial 65 nm techno logy developed by Tower Partners Semiconductor Co. (TPSCo). In order to bu ild detector elements larger than the reticle size\, a process called stit ching is used to join detector elements to build sensors up to 300 mm in l ength in a single wafer. Mechanical support is provided by carbon foam spa cers\, dramatically reducing the material budget in the region close to th e interaction point from the current $0.35\\%$ $X/X_0$ down to $0.05\\%$ $ X/X_0$ per layer. The new technology also provides improved power efficien cy below 20 mW/cm²\, only requiring the use of forced air for cooling. \n \nAt the core of the development\, the R&D process of the sensor ASIC pose s an entire new set of challenges mainly revolving around designing and va lidating the first wafer-scale silicon detector for high-energy physics. T o this purpose\, a submission named Engineering Run 1 has been delivered i n April 2023 that includes a large stitched detector prototype named Monol ithic Stitched Sensor (MOSS). MOSS is the first full-size stitched sensor demonstrator designed to validate manufacturing yield and feasibility of p ower and signal transmission. A custom readout system has been developed t o test the MOSS in all of its features and evaluate its functional yield a t a high level of granularity down to each single one of its 7 million pix els. This was a challenge in itself\, given the nearly 3000 connections ne eded to operate it and the expertise required to handle\, bond\, and mecha nically support such a huge and delicate sensor in a variety of use cases such as lab testing or test beams.

Fo r this\, the LHC will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of $7.5\\times 10^{34}$ cm$^{-2}$ s$^{ -1}$\, allowing the collection of more than 3 ab$^{-1}$ of data at $\\sqrt {s}=$13.6 (14) TeV. This unprecedented data sample will allow ATLAS to pe rform several precision measurements to constrain the Standard Model Theor y (SM) in yet unexplored phase-spaces\, in particular in the Higgs sector\ , a phase-space only accessible at the LHC. To benefit from such a rich data-sample it is fundamental to upgrade the detector to cope with the cha llenging experimental conditions that include huge levels of radiation and pile-up events. The ATLAS upgrade comprises a completely new all-silicon tracker with extended rapidity coverage that will replace the current inne r tracker detector\; a redesigned trigger and data acquisition system for the calorimeters and muon systems allowing the implementation\n of a free- running readout system. Finally\, a new subsystem called High Granularity Timing Detector\, will aid the track-vertex association in the forward reg ion by incorporating timing information into the reconstructed tracks. A f inal ingredient\, relevant to almost all measurements\, is a precise deter mination of the delivered luminosity with systematic uncertainties below t he percent level.

The detector is composed of small square pads with about 1mm p er side of Low Gain Avalanche Detector (LGAD) silicon sensors\, intended t o be placed in the ATLAS detector forward shielding at about 16m from the interaction point.\nThe detector is innovative in several aspects: It does not need an external cooling system\, and its readout preamplifiers are m eant to be placed at about 25m distance from the sensors\, in an area in w hich the radiation levels for the electronics can be neglected. Moreover\, the tiny acceptance of the small pads is supposed to minimize systematic effects in the luminosity determination due to pile-up of several interact ions in a single or consecutive proton-bunch crossings.\nA two-channels pr ototype of the detector has been installed already for Run 3 of the LHC an d recorded data in the year 2022. A modified version is set up for data-ta king in the current year 2023.\nThe talk will present the technical detail s of the project regarding the sensors\, their cooling\, and the readout s ystem.

The expected performance will improve the pointing resolution of the tracking\, particularly at lo w transverse momentum\, hence significantly extending the heavy flavour ph ysics program of the experiment. \n\nThe full detector consists of two hal f-barrels\, each containing three sensors\, of the size up to ~26 cm x ~10 cm\, bent in a half-cylindrical shape\, spaced by 6 mm in a concentrical configuration\, covering a pseudo rapidity acceptance up to ±2.5 (layer 0 ). The development of a wafer size MAPS sensor is based on 65 nm technolog y\, using the stitching technique to allow for a sensor size exceeding the technologies reticle size. A sensor thickness of less than 50 um and the usage of extremely light support structures based on carbon foam and air c ooling allow reducing the material budget per layer to the order of 0.05% X/X_0 in the detector active area. Replacement of the beam pipe allows pla cing the first detector layer only 1.8 cm far from the interaction point. \n\nThe contribution will describe the global detector integration concept \, focusing on: the sensor bending procedure at different thicknesses to t he target radii\, the electrical interconnection techniques via wire-bondi ng and the choice of the best carbon foam\, in terms of material density a nd thermal dissipation properties\, as light mechanical supporting structu res. Details on the electrical characteristics and mechanical integration of the flexible circuits designed to provide power and communication with sensors will be discussed\, as well as findings from the study of the cool ing by air at the expected dissipated power.

This calorimeter also feeds the\n ATLAS trigger to identify interesting events. In order to enhance the\n ATLAS detector physics discovery potential\, in the blurred environment\n created by the pileup\, an excellent resolution of the deposited energy\ n and an accurate detection of the deposited time is crucial.\n\n The computation of the deposited energy is performed in real-time using\n de dicated data acquisition electronic boards based on FPGAs. FPGAs are\n c hosen for their capacity to treat large amount of data with very low\n l atency. The computation of the deposited energy is currently done\n usin g optimal filtering algorithms that assume a nominal pulse shape of the\n electronic signal. These filter algorithms are adapted to the ideal\n situation with very limited pileup and no overlap of the electronic\n pu lses in the detector. However\, with the increased luminosity and pileup\, \n the performance of the optimal filter algorithms decreases significan tly and\n no further extension nor tuning of these algorithms could reco ver the\n lost performance.\n\n The off-detector electronic boards for the Phase-II Upgrade of the LAr\n calorimeter will use the next high-en d generation of INTEL FPGAs with\n increased processing power and memory . This is a unique opportunity to\n develop the necessary tools\, enabli ng the use of more complex\n algorithms on these boards. We developed se veral neural networks (NNs) with\n significant performance improvements with respect to the optimal\n filtering algorithms. The main challenge i s to efficiently implement these\n NNs into the dedicated data acquisiti on electronics. Special effort was\n dedicated to minimising the needed computational power while optimising the NNs\n architectures.\n\n Five NN algorithms based on CNN\, RNN\, and LSTM architectures will be\n pre sented. The improvement of the energy resolution and the accuracy of\n t he deposited time compared to the legacy filter algorithms\, especially\n for overlapping pulses\, will be discussed. The implementation of these\ n networks in firmware will be shown. Two implementation categories in\n VHDL and Quartus HLS code are considered.

Since the Q-value of the decay is divided only between charged particles\, the electron sum energy spectrum of the NLDBD would show a si ngle peak at the Q-value point. While only a few isotopes undergo double-b eta decay with the emission of two anti-neutrinos\, Xe-136 was chosen for the experiment due to its high natural abundance and suitability for use i n gaseous TPC detectors. However\, the Q-value for Xe-136 (~2.5MeV) can be contaminated by background radiation\, which needs to be distinguished fr om the signal.\nThe PandaX-III experiment uses a Time Projection Chamber ( TPC) detector filled with 10 bar gaseous Xe-136 and a readout plane consis ting of 52 Thermal-bonded Micromegas modules (TBMM) [1]\, each with readou t pixels connected in channels. There are 128 readout channels per module: 64 per X and Y directions. Therefore\, XZ and YZ projections of the initi al decay event track represent the detector output. It stores not only the amplitudes of the signal deposited by ionized particles inside the gas bu t also the topology of the event. Thus\, such data configuration is benefi cial for background discrimination from the signal [2]. In NLDBD searches\ , the experiment requires excellent energy resolution to discriminate sign als from the background\, and the PandaX-III experiment design aims to ach ieve better than 3% at 2.5 MeV. However\, in the real-world experiment\, r eadout channels may be disconnected due to physical damage\, the appearanc e of sparks\, high dark currents\, and other factors\, resulting in losses in energy measurement and track reconstruction. In addition\, the signal gain may be inhomogeneous on the Micromegas modules\, further degrading th e energy reconstruction. To improve the measurement quality\, registered d ata should be corrected for missing channels and inhomogeneities.\nIn this project\, Machine Learning techniques have been implemented to predict th e total energy of events detected by TBMM modules that have missing channe ls. Additionally\, event classification was studied to differentiate betwe en NLDBD events and background events based on their topology. To conduct the analysis\, Monte-Carlo simulations were performed using REST software based on the Geant4 and ROOT libraries. Multiple Neural Network (NN) archi tectures were tested to find the most optimal configuration that yields th e best predictions. The results indicate an improvement in the detection e fficiency of an NLDBD signal when NN is applied to correct missing energy compared to direct signal detection with missing energies. Finally\, discr imination of the background using NN demonstrates noticeable results\, hel ping select events that require reconstruction due to detector flaws. Such a technique shows excellent potential in implementation in Micromegas-bas ed experiments. After having presented the experiment and the status of th e MM readout\, the methodology of the ML studies will be described along w ith the corresponding results.\n\n*References\n[1] J.

During the Long Shutdown 3 (2026-2028)\, ATLAS and CMS silicon tracking systems will be entirely replaced and the m ain design goals include the capability to deal with high hit and data rat es\, the increase in granularity\, and improved radiation tolerance to cop e with fluences of up to $2\\times10^{16 }\\:n_{eq}/cm^2$ and a Total Ioni zing Dose (TID) of up to 1 Grad.\n\nThe RD53 collaboration has been worki ng since 2014 on the development of pixel chips for the future CMS and ATL AS upgrades. This work has recently led to the development and submission of the ATLAS RD53 production chip (ITkPixV2) which is using the 65 nm CMOS process and containing 153600 pixels of $50~\\mu m \\times 50~\\mu m$.\n\ nSeveral TID test campaigns with Xray sources were already done on the ful l-size pre-production chip under low temperature (same conditions as for t he inner detector) and have shown that the chip continues to work correctl y up to 1 Grad. However\, these tests have shown that some analog voltage and current values can shift by about 8%. It is therefore important to mon itor the different sensitive voltages and currents in the chip in order to measure the variation and possibly adjust them if necessary.\n\nThe monit oring system implemented in the RD53 front-end chip is based on a 12-bit A DC associated with a multi-channel multiplexer. It allows the digitization of different sensitive parameters in the chip\, particularly the voltages issued from the on-chip temperature sensors required for the off-line tem perature calculation. The dependence of the ADC reference voltage ($V_{ref ADC}$) on the total ionizing dose results in a high drift of the temperatu re measured through the ADC\, making the measurement unacceptable. \n\nA n ew temperature measurement approach not dependent on the $V_{refADC}$ shif t is proposed. It provides more precise temperature measurement even at hi gh radiation levels. Based on this\, a correction method for the $V_{refAD C}$ value is foreseen to be applied regularly during the operation of the pixel detector to increase the accuracy for the digitization of voltages o r currents in the RD53 chip.\n\nThe purpose of this presentation is to giv e a general overview of the RD53 chip architecture\, in particular the mon itoring system implemented inside the chip. Next\, the TID test results fo r the monitoring bloc are presented to show that the shift of the $V_{refA DC}$ due to the TID has the most significant impact on the measurement acc uracy and results in an unacceptable loss of accuracy for temperature meas urement. Afterwards\, the new temperature measurement approach that does n ot use the $V_{refADC}$ value is presented to show that better accuracy ca n be achieved. Finally\, the method to be followed to ensure more accurate voltages and currents monitoring despite dose effects on the ADC referenc e voltage is shown and discussed.\n\nhttps://indico.tlabs.ac.za/event/112/ contributions/3174/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/3174/ END:VEVENT BEGIN:VEVENT SUMMARY:Diamond XBPM Detector System for the HEPS(High Energy Photon Sourc e \,China) DTSTART;VALUE=DATE-TIME:20230907T092000Z DTEND;VALUE=DATE-TIME:20230907T094000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2818@indico.tlabs.ac.za DESCRIPTION:Speakers: Zhenjie Li (Institute of High Energy Physics\,CAS)\n High Energy Photon Source (HEPS) is a high-performance and high-energy syn chrotron radiation light source with a beam energy of 6GeV and an ultra-lo w emittance of better than 0.06nm.rad.

A key component of the CMS Beam Radiation Instrumentation and Luminosity system is a stand-alone luminometer\, the Fast Beam Condition Monitor (FBCM)\, which is fully independent from the C MS central trigger and data acquisition services and able to operate at al l times with an asynchronous readout. FBCM utilizes a dedicated front-end ASIC to amplify the signals from CO2-cooled silicon-pad sensors with a few nanoseconds timing resolution also enabling the measurement of beam-induc ed background. Front-end (FE) electronics are subject to high radiation co nditions with an expected 1 MeV neutron equivalent fluence of about 2.5e15 at the sensor location\, thus all components are radiation hardened: sens ors\, ASICs\, high-speed optical transceivers and voltage regulators. FBCM uses a modular design with two half-disks of twelve modules at each end o f CMS\, with 4 service modules placed around the disk edge at a radius of reduced radiation fluence. The electronics system design adapts several co mponents from the CMS Tracker for power\, control and read out functionali ties. The dedicated FBCM ASIC contains 6 channels with 600e- ENC and adjus table shaping time to optimize the noise with regards to sensor leakage cu rrent. Each channel outputs a single binary high-speed asynchronous signal carrying the Time-of-Arrival and Time-over-Threshold information. The chi p output signal is sent via a radiation-hard gigabit transceiver and an op tical link to the back-end electronics for analysis. The ASIC has slow con trol for internal testability features\, calibration and configuration reg isters access. A dedicated test system is designed for the FBCM FE electro nics\, it provides a modular and flexible setup for all testing needs thro ughout the project stages: initial ASIC validation test\, irradiated senso r and ASIC tests and system level testing with the full read-out chain.

The former oper ating principle is used: a very precise DC current is stored in an inducto r when this current is switched off it generates a precise pulse injected in the readout electronics. This is achieved by two different chips: the f irst one\, in TSMC 130nm technology\, provides the 16-bit current DAC as w ell as the calibration management system (I2C slow control and commands to obtain pulses)\; the second chip\, in XFAB 180nm technology\, embeds four high-frequency switches (1GHz) to generate the fast pulses for calibratio n.

Among str ategies developed by CERN Gas Team to reduce GHG emissions\, one branch is focused on studying alternative gas mixtures and one on recuperating gase s from gas mixtures used in the detectors. Firstly\, R-1234ze is investiga ted as a potential replacement for R-134a\, with additional tests explorin g the necessity of a fourth gas to maintain the same working point range a s R-134a based gas mixture. The performance of RPCs with R-1234ze was eval uated at different gamma rates in the presence of a muon beam at the CERN GIF++ facility by measuring efficiency\, streamer probability\, induced ch arge\, cluster size\, and time resolution. Secondly\, adding CO2 to the st andard gas mixture is studied as a mid-term solution to reduce R-134a usag e and decrease CO2-equivalent emissions by 15-20%. These gas mixtures were characterized using muon beams and gamma background at the GIF++ facility \, and an aging test is planned with the collaboration of EP-DT Gas team\, ATLAS\, and CMS RPC teams. This mid-term solution is particularly relevan t to the ATLAS RPC system\, as its leak rate disallows the use of a recupe ration system. The third strategy involves the development of an R-134a re cuperation system for the standard gas mixture\, with a prototype tested i n 2020-2021 and a production version under operation at CMS. This recupera tion system separates and recuperates R-134a from the standard gas mixture with an efficiency of approximately 80%\, allowing the recovered gas to b e reused and injected into the system.\n\nhttps://indico.tlabs.ac.za/event /112/contributions/2960/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/2960/ END:VEVENT BEGIN:VEVENT SUMMARY:Design and Implementation of the TDAQ System for the JUNO-TAO Dete ctor DTSTART;VALUE=DATE-TIME:20230904T145000Z DTEND;VALUE=DATE-TIME:20230904T151000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2799@indico.tlabs.ac.za DESCRIPTION:Speakers: Xiaolu Ji (IHEP)\nThe Taishan Antineutrino Observato ry (TAO or JUNO-TAO) will be deployed next to a core of the Taishan Nuclea r Power Plant to measure the reactor neutrino spectrum precisely as a refe rence spectrum for JUNO.

In parallel with needing la rger detectors to collect more data\, future experiments further require a significant reduction of systematic uncertainties with respect to what is currently available. In the neutrino oscillation measurements from the T2 K experiment\, the systematic uncertainties related to neutrino interactio n cross sections are currently dominant. To reduce this uncertainty\, a si gnificantly improved understanding of neutrino-nucleus interactions is req uired. In particular\, it is crucial to better characterise the nuclear ef fects which can alter the final state topology and kinematics of neutrino interactions in such a way which can bias neutrino energy reconstruction a nd therefore bias measurements of neutrino oscillations. \n \nThe upgraded ND280 detector will consist of a totally active Super-Fine-Grained-Detect or (Super-FGD) composed of 2 million 1 cm$^3$ scintillator cubes with thre e 2D readouts\, two High Angle TPC (HA-TPC) instrumented with resistive Mi croMegas modules\, and six TOF planes. It will directly confront our know ledge of neutrino interactions thanks to its full polar angle acceptance a nd a much lower proton tracking threshold. Furthermore\, neutron tagging c apabilities\, in addition to precision timing information\, will allow the upgraded detector to estimate neutron kinematics from neutrino interactio ns. Such improvements permit access to a much larger kinematic phase space which correspondingly allows techniques such as the analysis of transvers e kinematic imbalances\, to offer remarkable constraints of the pertinent nuclear physics for T2K analyses.\n\nNew reconstruction algorithms are bei ng developed to fully benefit from the improved capabilities of the Super- FGD and of the HA-TPC and will be described in this talk together with the expected performances of the ND280 upgrade.\n\nhttps://indico.tlabs.ac.za /event/112/contributions/3192/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3192/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of the liquid scintillator for JUNO DTSTART;VALUE=DATE-TIME:20230905T140000Z DTEND;VALUE=DATE-TIME:20230905T142000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2804@indico.tlabs.ac.za DESCRIPTION:Speakers: Boxiang Yu (中国科学院高能物理研究所)\nT he Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose exp eriment designed to elucidate fundamental neutrino properties\, study neut rinos with astrophysical or terrestrial origins\, and search for rare proc esses beyond the Standard Model of particle physics. Its central detector is a 20 kton liquid scintillator (LS) located 650 m underground in Guangdo ng\, China. To achieve its physics goals\, the JUNO LS must have high tran sparency and ultra-low radiation background. To purify the LS\, five plant s were designed: alumina filtration\, distillation\, mixing\, water extrac tion\, and steam stripping. In addition\, two corollary plants were design ed to supply ultra-pure water and high purity nitrogen for the liquid scin tillator purification system. Currently\, the construction of the seven pl ants is almost completed\, and the commissioning of the plants is underway .\n\nhttps://indico.tlabs.ac.za/event/112/contributions/2804/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2804/ END:VEVENT BEGIN:VEVENT SUMMARY:ATLAS ITk Pixel Detector Overview DTSTART;VALUE=DATE-TIME:20230906T100000Z DTEND;VALUE=DATE-TIME:20230906T102000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2963@indico.tlabs.ac.za DESCRIPTION:Speakers: Koji Nakamura (CERN)\nIn the high-luminosity era of the Large Hadron Collider\, the instantaneous luminosity is expected to r each unprecedented values\, resulting in up to 200 proton-proton interacti ons in a typical bunch crossing. To cope with the resulting increase in oc cupancy\, bandwidth and radiation damage\, the ATLAS Inner Detector will b e replaced by an all-silicon system\, the Inner Tracker (ITk). The innermo st part of the ITk will consist of a pixel detector\, with an active area of about 13 m2. To deal with the changing requirements in terms of radiati on hardness\, power dissipation and production yield\, several silicon sen sor technologies will be employed in the five barrel and endcap layers. Pr ototype modules assembled with RD53A readout chips have been built to eval uate their production rate. Irradiation campaigns were done to evaluate th eir thermal and electrical performance before and after irradiation. A new powering scheme – serial – will be employed in the ITk pixel detector \, helping to reduce the material budget of the detector as well as power dissipation.

A dedi cated\, magnetic-field resistant DC-DC converter provides both 1.2 and 2.5 V to the EoS using the rad-hard bPol ASICS from CERN.

The detector conceptua l design of a updated detector consists of a tracking system\, which is a high precision (about 100μm) spatial resolution Time Projection Chamber ( TPC) detector as the main track device in very large 3D volume. The tracki ng system required the high precision performance requirements\, but witho ut power-pulsing not likely as the International Linear Collider (ILC)\, w hich leads to additional constraints on detector specifications\, especial ly for the case of the machine operating at the high luminosity Z pole (Te ra Z). TPC detection technology requires longitudinal time resolution of a bout 100ns and the physics goals require Particle Identification Detection (PID) resolution of very good separation power with cluster counting to b e considered. A number of critical issues are still remaining regarding th e TPC research. The simulation and PID resolution show TPC technology pote ntial to extend Tera Z at the future e+e- collider.\nIn this talk\, I will present the feasibility and status of high precision TPC as the main trac k detector for e+e collider. The traditional pad readout is designed about 1mm x 6mm and the pixelated readout is designed about 55μm x 5μm or big ger size. Compared with the pad readout\, the pixelated readout option wil l obtain the better spatial resolution of single electrons\, the very high detection efficiency in excellent tracking and good dE/dx performance. A smaller prototype TPC has been developed with a drift length of 500 mm\, g aseous chamber\, 20000V field-cage\, the low power consumption FEE electro nics and DAQ have been commissioned and some studies have been finished.

In par ticular\, a collider with the centre-of-mass energy of 10 TeV is the long- term target of the ongoing design study\, while lower intermediate energie s are also considered. Featuring much smaller size and lower energy consum ption its discovery potential would be comparable to that of the FCC-hh wi th its 100 TeV centre-of-mass energy.\n\nOne of the biggest technical chal lenges at a Muon Collider experiment is designing a detector capable of de livering high physics performance under the extremely intense beam-induced background (BIB) that originates from the muon decays along the collider ring. It is particularly challenging in the tracking detector\, where hit density can reach 1000 hits/cm^2 close to the interaction region at the to tal ionising dose of ~1 Mrad/year. It is therefore necessary to design the tracking detector such that effective mitigation of background can be ach ieved to make full event reconstruction feasible.\n\nThis contribution pre sents the latest results from a full-simulation study on the optimal desig n of a Muon Collider tracking detector. It includes the nominal performanc e figures obtained from simulations together with the most promising BIB-m itigation strategies\, and an overview of promising technologies compatibl e with this detector design.\n\nhttps://indico.tlabs.ac.za/event/112/contr ibutions/3230/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3230/ END:VEVENT BEGIN:VEVENT SUMMARY:R&D status for an innovative crystal calorimeter for the future Mu on Collider DTSTART;VALUE=DATE-TIME:20230907T142000Z DTEND;VALUE=DATE-TIME:20230907T144000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-2769@indico.tlabs.ac.za DESCRIPTION:Speakers: Ivano Sarra (Istituto Nazionale di Fisica Nucleare - LNF)\nThe Crilin calorimeter is a semi-homogeneous calorimeter based on L ead Fluoride (PbF2) Crystals readout by surface-mount UV-extended Silicon Photomultipliers (SiPMs). It is a proposed solution for the electromagneti c calorimeter of the future Muon Collider. A high granularity is required in order to distinguish signal particles from the background and to solve the substructures necessary for jet identification. Time of arrival measur ements in the calorimeter could play an important role\, since very large occupancy due to beam-induced backgrounds is expected\, and the timing cou ld be used to identify energy depositions compatible with the expected muo n-muon interaction time. The calorimeter energy resolution is also fundame ntal to measure the kinematic properties of jets. Moreover\, the calorimet er should also operate in a very harsh radiation environment: 1 Mrad/year total ionizing dose (TID) and a 10^14 neutron 1MeV/cm^2/year equivalent ne utrons fluence. Our radiation hardness studies on crystals and SiPMs\, hav e demonstrated we can work in this environment both for dose and neutron f luences.\nA dedicated test beam\, on single cell prototype (Proto-0)\, has been performed at CERN H2 in August 2022 with an electron energy of 120 G eV: a timing resolution better than 50 ps has been achieved for energy dep osits greater than 1 GeV. \nIn order to validate the design choices\, the proposal is to build a larger prototype\, called Proto-1. The design has b een optimized with the simulation studies starting from dimensions of 0.7 R𝑀 and 8.5 X0 (∼ 0.3𝜆). This size comes from a compromise of an ac ceptable containment of 100 GeV electrons and cost constraints. Results wi ll be extrapolated to the optimum length of the Muon Collider calorimeter of the order of 20 X0.\nThe proposal is to build Proto-1 with two layers o f 3 × 3 PbF2 crystals\, each read out with UV-extended SiPMs (Hamamatsu S 14160-3010 PS SMD sensors) as already done in Proto-0. These new SiPMs wer e already tested with an ultra-fast blue laser (400 nm\, 100 ps) and the n ew electronics front-end (FEE) that showed a dynamic range from 0 to 2 V\, a rise time of ∼ 2 ns with full signal in ~ 70 ns and a time resolution less than 50 ps even at a charge as low as 100 pC (∼ 250 Np.e.). The pr oto-1 operational temperature will be 0/−10◦C and the performance will be validated in a dedicated test beam. Specifically\, our goals are: 1) p erform a complete operational test of the prototype\, including operation with cooling\; 2) obtain data for a complete analysis of digitized signals from the detector for electrons and minimum-ionizing particles\; 3) test the cluster reconstruction capability and measure the time resolution\; 4) measure longitudinal and transverse shower profile and compare with resul ts obtained in simulation. \nDetails about the prototype mechanics and ele ctronics will be shown\; Proto-1 will be tested in a dedicated test beam a t Cern before the end of 2023.\n\nhttps://indico.tlabs.ac.za/event/112/con tributions/2769/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2769/ END:VEVENT BEGIN:VEVENT SUMMARY:New Ideas on ILC Detector Technologies & Sustainability Studies fo r Linear Colliders DTSTART;VALUE=DATE-TIME:20230907T092000Z DTEND;VALUE=DATE-TIME:20230907T094000Z DTSTAMP;VALUE=DATE-TIME:20260306T091343Z UID:indico-contribution-112-3261@indico.tlabs.ac.za DESCRIPTION:Speakers: Maksym Titov (CEA Saclay Irfu)\nAmong all “Higgs F actories”\, the international Linear Collider project (ILC) with a first stage at 250 GeV\, followed by an upgrade to higher energy\, is by far th e most advanced in terms of technology\, maturity\, cost\, and preparation s in international cooperation.

All this at a single circular collider and on a feasible timescale\, as reviewed in the frame of the European Roadmap for Accelera tor R&D and during the U.S. Snowmass process. The recently formed Internat ional Muon Collider Collaboration\,\nhosted at CERN\, targets the design o f a muon collider facility with a center of mass energy of 10 TeV or highe r\, which seem feasible and\nsustainable with technologies that can be mad e available in the near future. Currently a 3 TeV stage is considered viab le as a post HL-LHC facility.\nThe main challenges are to produce bright m uon beams\, while facing the drawback arising from the short muon lifetime at rest. The detector design\,\nthe choice of the technologies\, and reco nstruction algorithms are heavily influenced by the beam-induced backgroun d (BIB). A dedicated design\nof the machine detector interface is required to mitigate an unprecedented amount of secondary and tertiary decay produ cts of muons beams at the interaction point.

According to the latest update of the Europe an Strategy for Particle Physics\, the first stage of the project will be the construction of an approximately 90 km circular tunnel\, instrumented with an e+e- collider based on established technologies. This would allow for an extensive physics program\, realized at center-of-mass energies spa nning the range from the Z resonance up to a t-tbar threshold. Such a mach ine\, called FCC-ee\, would provide a clean experimental environment\, pro ducing high luminosity for precision measurements of the Higgs boson\, W a nd Z bosons\, and the top-quark. Precision searches will test the consiste ncy of the Standard Model and push the sensitivity to new physics at high scales. Direct searches for new particles\, including dark matter\, are al so feasible. \nThe tunnel can then be reused for a proton-proton collider (FCC-pp)\, collecting data in the range of 100 TeV. Such a machine would o ffer a vast program of measurements of the Standard Model observables and a huge potential of direct searches for new particles.\nDuring the talk\, both the aspects of the
