摘　　要：研究了多种包装材料和包装工艺对钨酸铅(PbWO4)晶体光输出和能量分辨的影响,测量结果与基于GEANT4的模拟结果符合很好,并由此确定了晶体的最佳包装方法。The light output and energy resolution of PbWO4 crystal are studied with different wrapping materials and methods.The Wrapping condition was optimized by analyzing the experimental data to gain higher light output and better energy resolution.A GEANT4-based package has been developed to simulate the corresponding features of PbWO4 crystal,and the simulation results are consistent with the experimental data.
