The ILD tracking system consists of a Si verte x detector\, forward tracking disks\, and a large volume Time Projection C hamber (TPC)\, all embedded in a 3.5 T solenoidal field. The TPC is design ed to provide up to 220 three dimensional points for continuous tracking w ith a single-hit resolution better than 100 μm in rφ\, and about 1 mm in z. An extensive research and development program for a TPC has been carri ed out within the framework of the LCTPC collaboration. A Large Prototype TPC in a 1 T magnetic field\, which allows to accommodate up to seven iden tical Micropattern Gaseous Detector (MPGD) readout modules of the near-fin al proposed TPC-design\, has been built as a demonstrator at the 5 GeV ele ctron test-beam at DESY. Three MPGD concepts are being developed for the T PC: Gas Electron Multiplier\, Micromegas and Pixel\, also known as GridPix (MicroMegas integrated on a Timepix chip). Successful test beam campaigns with the different technologies have been carried out during the last dec ade. Fundamental parameters such as transverse and longitudinal spatial re solution and drift velocity have been measured. In parallel\, a new gating device based on large-aperture GEMs has been successfully developed. Rece nt R&D also led to a design of a Micromegas module with monolithic cooling plate in 3D printing and 2-phase CO2 cooling. In this talk\, we will revi ew the track reconstruction performance results and summarize the next ste ps towards the TPC construction for the ILD detector. The TPC with pad (pi xel) readout electronics is designed to have about 10e6 pads (10e9 pixels) per endcap for continuous tracking and a momentum resolution of delta(1/p T) ~ 1x10e-4/GeV (TPC only) (delta(1/pT)~0.8x10e-4}/GeV (60% coverage\, TP C only))\, and the dE/dx resolution is ~5 % (~4 %). The momentum resolutio n including all tracking subdetectors is 2x10e-5/GeV.\n\nhttps://indico.tl abs.ac.za/event/112/contributions/2823/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2823/ END:VEVENT BEGIN:VEVENT SUMMARY:FCC detector concepts DTSTART;VALUE=DATE-TIME:20230907T100000Z DTEND;VALUE=DATE-TIME:20230907T102000Z DTSTAMP;VALUE=DATE-TIME:20260411T024427Z UID:indico-contribution-529-2774@indico.tlabs.ac.za DESCRIPTION:Speakers: Paolo Giacomelli (INFN Bologna)\nThe Future Circular Colliders (FCC) project is centered on the construction of a large\, 91 k m in circumference\, circular tunnel located around the Geneva area. The p roject foresees two distinct phases of operation. In the first one\, denom inated FCC-ee\, the tunnel will house an electron positron collider. FCC-e e will be operated at several center-of-mass energies\, ranging from the Z peak to the WW production threshold\, to the Higgs boson production peak (~ 250 GeV)\, and then to just above the ttbar production threshold (~365 GeV). FCC-ee promises exceptionally high luminosities\, beyond 10$^{36}$ cm$^{-2}$s$^{-1}$ at the Z peak and will allow to explore with unprecedent ed precision the electroweak sector while also producing a sample of more than a million Higgs boson events in very clean experimental conditions. I n a second phase\, denominated FCC-hh\, the tunnel will instead house a pr oton-proton collider with the aim of producing the highest possible collis ion energies\, up to more than 100 TeV in the center-of-mass. \nSuch a cha llenging project calls for extremely high-performance detectors being able to study all the many channels of interesting physics that both FCC-ee an d will FCC-hh will unravel. Especially for FCC-ee there are already three different detector concepts that are being studied and that will be presen ted. FCC-ee will in fact have four interaction points that could house eac h a different detector. There is a significant detector R&D program that h as started since a few years in order to optimize and improve the detector concepts for the best possible exploitation of FCC-ee. Many different tec hnologies\, going beyond the state-of-the-art in the field\, are being inv estigated for the various subdetector components. The final detectors will likely be a mix and match of the currently investigated technologies.\nFC C-hh is farther in the future and presents extremely challenging experimen tal conditions\, nevertheless a possible detector concept has been devised and will also be presented.\n\nhttps://indico.tlabs.ac.za/event/112/contr ibutions/2774/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2774/ END:VEVENT BEGIN:VEVENT SUMMARY:Tracking-detector design for a multi-TeV Muon Collider DTSTART;VALUE=DATE-TIME:20230907T102000Z DTEND;VALUE=DATE-TIME:20230907T104000Z DTSTAMP;VALUE=DATE-TIME:20260411T024427Z UID:indico-contribution-529-3230@indico.tlabs.ac.za DESCRIPTION:Speakers: Nazar Bartosik (INFN Torino)\nA multi-TeV **Muon Col lider** is a promising candidate for the next energy-frontier facility\, c ombining in a single machine usually competing features\, such as high ene rgy reach\, clean final states\, and small environmental footprint. 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: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:20260411T024427Z UID:indico-contribution-529-3261@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. A global design and R&D effort for baselin e detector concepts\, ILC and SiD\, allowed drawing up the main specificat ions for the detector performance. Intentionally\, ILD and SiD concept gr oups did not make specific choices and keep various options for technologi es open to realize the individual sub-detectors. This has an advantage tha t the technologies can be further matured until specific choices will be m ade once the project is approved. Several promising new ideas for improved sensors and detector systems that can be integrated into ILD and SiD will be discussed in this talk. Recent developments are ongoing to adapt eleme nts of ILD concept that might need to be changed\, should ILD operates at other circular Higgs Factory colliders.\n\nThis talk will also highlight t he challenges and necessary technological advances for detector optimizati on\, further R&D work on critical accelerator technologies within the ILC International Technology Network (ITN)\, and address sustainability aspect s for future Linear Collider facilities.\n\nhttps://indico.tlabs.ac.za/eve nt/112/contributions/3261/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3261/ END:VEVENT BEGIN:VEVENT SUMMARY:Challenges and concepts for a multi-TeV Muon Collider experiment DTSTART;VALUE=DATE-TIME:20230907T094000Z DTEND;VALUE=DATE-TIME:20230907T100000Z DTSTAMP;VALUE=DATE-TIME:20260411T024427Z UID:indico-contribution-529-3104@indico.tlabs.ac.za DESCRIPTION:Speakers: Massimo Casarsa (INFN)\nMuon colliders provide a uni que route to deliver high energy collisions that enable discovery searches and precision measurements to extend our understanding of the fundamental laws of physics. 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. From an initial detector conc ept and full simulation studies of data reconstruction performance and phy sics projections\nat 1.5 and 3 TeV\, we outline next steps in the developm ent of a multi-purpose detector for a muon collider with center-of-mass en ergies up to 10 TeV.\nThe status of the experiment design\, future plans f or R&D and synergies will be discussed.\n\nhttps://indico.tlabs.ac.za/even t/112/contributions/3104/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/3104/ END:VEVENT BEGIN:VEVENT SUMMARY:The Future Circular Collider Project and its Physics Programme DTSTART;VALUE=DATE-TIME:20230907T090000Z DTEND;VALUE=DATE-TIME:20230907T092000Z DTSTAMP;VALUE=DATE-TIME:20260411T024427Z UID:indico-contribution-529-2786@indico.tlabs.ac.za DESCRIPTION:Speakers: Tadeusz Lesiak (IFJ PAN Kraków)\nThe talk will prov ide a brief description of the proposed Future Circular Collider (FCC) pro ject and its physics program. 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 accelerator and physics program of the FCC project will be presented\, paying special attention to the e+e- stage\n\nhttps:/ /indico.tlabs.ac.za/event/112/contributions/2786/ LOCATION: Meeting Room 2.41 - 2.43 URL:https://indico.tlabs.ac.za/event/112/contributions/2786/ END:VEVENT END:VCALENDAR
