Abstract :
We investigated the nuclear counter effect of the silicon PIN photodiode mounted on a CsI(Tl) crystal array as a result of the leakage of electromagnetic shower through the rear end of the crystal. Using 1 and 2 GeV electron beams at KEK, we estimated its effect on the energy measurement by the CsI(Tl) calorimeter of BELLE experiment. The results are found to be in good agreement with that of GEANT simulation and the expected effect for the BELLE calorimeter is negligible.
