Abstract

Silicon Avalanche Photo-diodes (APDs) 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 x 10(13) neutrons/cm(2) under a severe radiation environment. In this study, we studied on the effect of photo-statistical fluctuations from those of neutrons by using Geant4 toolkit. (C) 2012 Elsevier B.V. All rights reserved.
