Description
Although SiPMs have become an attractive photodetector for LHC and future HL-LHC detector systems, the levels of radiation exposure (ie up to 2 e14 neq/cm^2 in the case of the CMS Barrel timing layer) have motivated significant R&D on mitigating the consequences of increased leakage current/Dark Counts. The challenge for signal processing is that ~GHz levels of Dark Counts result in a noise background which, in the frequency domain, has similar characteristics to the signal (so-called "1/f noise"). We demonstrate a technique for mitigating the degradation of time resolution that could be applied to the CMS LYSO/SiPM design, due to this noise term.
