摘　　要：引力波暴高能电磁对应体全天监测器由两颗相同的微小卫星组成,旨在完成对引力波事件伴随出现的伽马射线及其他高能天体暴发事例。作为主要载荷,GRD探测器使用LaBr3晶体耦合SiPM阵列探测X/γ射线。本文主要利用广角康普顿散射符合技术研究其电子能量响应特性。结果表明,双掺溴化镧的GRD探测器对伽马与电子的响应在低能区,随能量减小而增加。The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor(GECAM)is composed of two identical microsatellites.Its main goal is to complete the monitoring of the Gamma-Ray Bursts(GRBs)coincident with Gravitational Wave(GW)events and other high-energy celestial bodies outbreak instances.As the main load,the GRD detector uses LaBr3 crystal coupled SIPM array to detect X/γray.In this paper,the electron energy response characteristics are studied by wide-angle Compton scattering coincidence technique.The results show that the response of double lanthanum bromide doped GRD detector to gamma and electron increases with the decrease of energy in the low energy region.
