Calorimeters have recently evolved to provide much more granularity in order to better identify particles inside showers and improve the energy resolution, in particular for jets. “Imaging calorimetry” has been studied in detail by the CALICE collaboration since the mid 2000s and more recently chosen by the CMS experiment to equip its endcap calorimeter. Imaging calorimetry increases by one...
A custom Application Specific Integrated Circuit (ASIC) TIGER (Turin Integrated Gem Electronics for Readout) is capable of simultaneous precise measurements of both the charge and time characteristics of signals in gaseous detectors. Flexibility of TIGER operation parameters makes it attractive to be evaluated as a front-end electronics solution for Straw-based Trackers of future High Energy...
The LHC upgrade at CERN implies an increase in the dynamic range for the electromagnetic liquid argon (Lar) calorimeter of the ATLAS detector, a change in the power supply system and an increase of the luminosity and thus of radiation effects on detectors. This requires completely redoing the Lar calibration system. The new system should provide a 16-bit range current (from 625 nA to 320 mA)...
The HKROC ASIC was originally designed to readout the photomultiplier tubes for the Hyper-Kamiokande experiment. HKROC is an auto-triggered very versatile and innovative ASIC capable of readout a large number of channels while meeting very stringent requirements in terms of noise, time & charge resolution while sustaining very high hit-rate and low-power consumption.
Each HKROC channel...
The High-Luminosity LHC upgrade aims to increase the instantaneous luminosity of the LHC machine to a nominal value of $5\times10^{34}\:cm^{-2}s^{-1}$. During the Long Shutdown 3 (2026-2028), ATLAS and CMS silicon tracking systems will be entirely replaced and the main design goals include the capability to deal with high hit and data rates, the increase in granularity, and improved radiation...
SiPMs (also known as MPPCs) are becoming widely used in HEP experiments thanks to their excellent photon counting performance, compactness, and immunity to magnetic fields.
Powering these devices, apparently simpler than high-voltage photosensors, still poses several challenges due to the dependence of their performance on bias voltage and the significant increase of leakage current after...
