摘要
本文介绍ｓ５３４５型雪崩光电二极管用于ＣｓＩ（Ｔｌ）晶体光信号的读出，测量了γ射线的能谱，对应于￣（２２）Ｎａ的１．２７ＭｅＶ的入射能量，得到６．８％的能量分辨率。并对能量分辨率与光耦合面积及晶体尺寸、成形时间、偏压的关系等进行了测量。将雪崩光电二极管和ＣｓＩ（Ｔｌ）晶体组成一种新型的闪烁探测器的实验研究这在国内尚属首次。
Using S5345 type of avalanche photodiode produced by Hamamatsu for the CsI (Tl)crystal readout,thespectrum of γ ray were measured.Energy resolution of 6.8%for 1.27 MeV γ ray from ￣(22)Na source was ob-tained.The relation between energy resolution and coupling area, dimension of crystal, shaping time and biaswere measured. This type of detector was studied experimentally for the first time in China.(
