【摘要】 为满足大型巡天望远镜中广角大气荧光/切仑科夫光探测器阵列研制的需求,设计了大型复合实验阵列(LHAASO)广角大气荧光/切仑科夫光探测器阵列(WFCTA)电子学读出系统。该系统负责处理PMT阵列的输出信号,总共由三部分组成:模拟电路AB(Analog Board)、数字电路DB(Digital Board)、触发电路BDB(Bus Driver Board)。本文介绍了模拟电路和数字电路的设计,并测试了相对偏差和分辨率指标。结果表明在最小信号处,该系统相对偏差小于4%,分辨率小于25%,到达设计要求。更多还原

【Abstract】 In order to meet the requirements of LHAASO-WFCTA, the readout electronics have been designed. The electronic readout system which processes the signal from PMT arrays is made up of 3 parts: the analog board(AB),the digital board(DB),and the bus driver board(BDB). The analog board and the digital board are discussed in this paper and we have measured the relative deviation and resolution. The results show that relative deviation is less than 4% and the resolution is less than 25% when we measure the smallest signal. Therefore this design is proper to the project.更多还原
