摘要
报道了用双维位置灵敏光电倍增管读出的ＣｓＩ（Ｔ１）探测器，其ＣｓＩ（Ｔ１）晶体厚度为１０ｍｍ，灵敏面积为６０ｍｍ×６０ｍｍ．探测器的空间位置分辨为０．８１ｍｍ（ＦＷＨＭ）．用蒙特卡罗的方法对该探测器作了进一步模拟研究，其结果与实际测试的结果很好地一致．
A CsI(T1) detector with a two-dimension posihonal sensitive photomultiplierreadout at Radioactive Ion Beam Line in Lanzhou (RIBLL) is reported. The Cs(T1)scitillator is 10 mm in thickness and 60mm×60mm in active area. Its spatialresolution of 0.81mm (FWHM) is achieved. Finally the Monte-Carlo method isemployed to simulate its spatial resolution whose result is in good agreement with thetested.
