摘要
研究了由于电磁簇射在CsI(T1)晶体后端的泄漏而引起的硅光二极管“核计数器”效应．通过GEANT模拟和实验测量分析其在BESⅢ的CsI(T1)晶体量能器中对能量测量的影响．
due to the have tested found to be We investigated the nuclear counter effect of the silicon photodiode mounted on a CsI（T1） crystal detector leakage of electromagnetic shower through the rear end of the crystal. Using electron beams at IHEP, we its effect on the energy measurement by the CsI（T1） calorimeter for BESⅢ experiment. The results are in good agreement with that of GEANT simulation and the effect for the BESⅢ calorimeter is negligible.
