In recent years, the gain suppression mechanism has been studied for large localized charge deposits in Low-Gain Avalanche Detectors (LGADs). LGADs are a thin silicon detector with highly doped layer that provides moderate internal signal amplification. Using CENPA Tandem accelerator at University of Washington, response different thicknesses to MeV-range energy from proton beam were studied. Three LGAD prototypes 50~$\mu$m, 100~$\mu$m, 150~$\mu$m characterized. The devices' was determined...
Abstract We present measurements of AC-LGADs performed at the Fermilab's test beam facility using 120 GeV protons. studied performance various strip and pad AC-LGAD sensors that were produced by BNL HPK. The are with our upgraded setup utilizes a high precision telescope tracker, simultaneous readout up to 7 channels per sensor, which allows detailed studies signal sharing characteristics. These allow us assess differences in designs between different manufacturers, optimize them based on...
We investigate the signal propagation in AC-LGAD (aka RSD), which are LGAD with a common N+ layer and segmented AC-coupled readout contacts, by measuring response to IR laser TCT on large selection of strip readout. The interest for this topic derives from realization that while charge sharing between neighboring strips is essential good position resolution, beyond next neighbor generates background signals general detrimental sensor goal low occupancy. Using produced Hamamatsu Photonics...
PIONEER is a next-generation experiment to measure the charged-pion branching ratio electrons vs. muons and pion beta decay with an order of magnitude improvement in precision. This will probe lepton universality at unprecedented level test CKM unitarity quantum loop level. was approved 2022 run PiE5 beamline PSI. A high-granularity active target (ATAR) being designed provide detailed 4D tracking information, allowing separation energy deposits products both position time. The chosen...
