摘　　要：为测试暗物质卫星塑闪阵列探测器的功能和性能指标,构建了塑闪阵列探测器地面标定系统,并研制了地面标定触发电路。该触发电路采用标准NIM插件,采用控制开关和可编程逻辑器件设计,具有输入输出可控、输出脉冲宽度及间隔可调、输出延时小、逻辑功能易于更改等特点,适用于构建对输出脉冲信号有特殊要求的触发系统。经地面宇宙线和束流标定实验检验,研制的标定触发电路满足设计要求。In order to test the functions and performance indexes of plastic scintillator array detector for dark matter explore satellite, a ground calibration system is constructed and a ground calibration trigger circuit is developed. The trigger circuit described in this paper is a standard NIM module designed with control switches and programmable logic device, its inputs and outputs can be controlled, and output pulse width and space are adjustable, the output delay is small, the logic function can be Changed easily. It is applicable to build a trigger system that has the special requirements for the output signals. The results of ground calibration experiments with cosmic rays and accelerator beam show that the ground calibration trigger circuit can well meet the design requirements.
