标题： Report on Spring8 Test

摘要： 伽马射线在6到38兆电子伏特的能量范围内被产生并送入新SUBARU设施中的两个大体积LaBr3(Ce)晶体（3.5x8英寸），目的是研究探测器的响应函数。 通过比较两个探测器的实验谱，我们推导出系统的线性，分别针对两个晶体和两个PMT及VD。 此外，进行了蒙特卡罗模拟以再现实验谱。 在准直束和各向同性源的情况下，也评估了光电峰和相互作用效率。 显示英文摘要

摘要： Gamma rays in the energy range from 6 to 38 MeV were produced and sent into two large volume LaBr3(Ce) crystals (3.5x8 inches) at the NewSUBARU facility, with the goal of investigating the response function of the detectors. By comparing the experimental spectra of the two detectors we deduced the linearity of the system, separately of the two crystals and of the two PMT and VD associated. Moreover, Monte Carlo simulations were performed in order to reproduce the experimental spectra. The photopeak and interaction efficiencies both in case of a collimated beam and an isotropic source were also evaluated.
