LightPix is designed for amplification, triggering, digitization, and multiplexed readout of high-channel count silicon photomultiplier (SiPM) systems, particularly within cryogenic environments. It is based around the LightPix application-specific integrated circuit (ASIC), a custom low-power cryo-compatible ASIC which provides 64 input amplifiers, self-triggering TDCs with O(ns) precision,...
We will present an experimentally verified model for characterising the photodetection efficiency of silicon photomultipliers (SiPMs). This work has been performed in the context of improving detector response for any SiPM based experiment requiring accurate photon simulations. The model is based on comprehensive measurements of photon detection efficiency for two UV sensitive Hamamatsu and...
Liquid Argon (LAr) Time Projection Chambers (TPC)s are promising detectors for dark matter search, due to their response uniformity, scalability to large target masses, and suitability for extremely low background operations. The Darkside-20k (DS-20k) experiment is a new dark matter detector under construction at INFN LNGS that aims to push the sensitivity for Weakly Interacting Massive...
The MEG II experiment searches for new physics like SUSY-GUT/SUSY-seesaw through the lepton flavor violating mu+ -> e+ gamma decay with ten times better sensitivity than the MEG experiment. The MEG experiment published the result of B(mu+ -> e+ gamma)<4.2x10-13 at 90% CL. in 2016, which was thirty times better result than the previous limit. While the MEG experiment utilized 846 2inch PMTs to...
nEXO is a next-generation 5-tonne liquid xenon (LXe) time projection chamber that will search for the neutrinoless double beta decay (0νββ) of Xe-136, which is a lepton number violating process that can occur if neutrinos are massive Majorana fermions. The experiment has a projected half-life sensitivity of 1.35 x 10^28 years over 10 years of livetime, which sets a design goal of 0.8% energy...
