Description

Silicon Avalanche Photodiodes (APD) working in proportional were chosen as a readout device for the PbWO4 crystals in the barrel of the CMS Electromagnetic Calorimeter (ECAL). During 10 years of operation, the CMS ECAL will be exposed to $2\times10^{13}$ neutrons/cm$^2$ under a severe radiation environment. In this study, we studied on the effect of photostatistical fluctuations from those of neutrons by using GEANT4 toolkit. Afterwards, the resulting photons have been tracked with a single-particle Monte Carlo simulation technique.
