资料介绍

为记录和分析塑闪阵列探测器(PSD)中塑闪单元条的有效输出信号,设计一款针对PSD塑闪单元条的标定触发电路。该触发电路由时间检出单元和逻辑触发单元组成,使用三路模拟电路实现对三路探测器的精确时间检出。通过现场可编程门阵列(FPGA)进行逻辑符合统计结果,并与上位机通信实现对定时电路的控制,可通过上位机配置阈值和设置符合通道。测试结果表明:该标定触发电路工作性能稳定,计数率高,通道一致性好,能够灵活配置逻辑,可满足使用要求。

For recording and analyzing the valid output signal of plastic scintillator bar,which placed in the Plastic Scintillator Detector Array(PSD),a Calibration and trigger circuit has been designed.The circuit contains time readout unit and logic trigger unit.The time readout unit is implemented with three channels of analog circuits to acquire the accurate timing result.After this unit,using a FPGA to implement the logic coincidence for the output signal,control the timing process and communicate with the host computer.The host computer can configurate the threshold and determine the channels to coincide.The circuit has been characterized in the lab and proven to satisfy the design requirement.The result shows that it has stable working performance,high counter rate,high uniformity in each channel and easy reconfiguration.
