摘要: 利用Litrani软件包[1]对钨酸铅(PbWO4或PWO)长晶体的光传导与光收集过程进行了模拟计算,着重讨论了晶体的吸收长度、表面处理等因素对光收集的影响,并对各向同性与各向异性的模拟作了比较.

关键词: 钨酸铅晶体, 光收集, 各向异性, 吸收长度, 表面处理

Abstract: In the electromagnetic calorimeter,longitude light collection uniformity of crystal scintillator has certain influence on the energy resolution.Monte Carlo (MC) method (using Litrani software package) is used to simulate the process of light transmission and collection in the long lead tungstate (PbWO4 or PWO) crystal.Discussion focused on the influence of the absorption length and the face management on the light collection is presented.And comparison between anisotropic simulation and isotropic simulation is made.

Key words: lead tungstate crystal, light collection, anisotropic medium, absorption length, face management
