一种基于数字示波器的能谱和时间联合测量系统

内容简介：以数字示波器作为数据采集设备建立了一套数字式辐射测量系统。该系统利用仪器控制程序实现实验控制与数据处理。仪器控制程序采用 VISA 技术和面向对象的 C＋＋程序设计技术开发，能够用于多种型号数字示波器。该系统能程控测量辐射探测器输出的脉冲信号、信号到达时间及存储与备份原始波形数据，实现了对粒子脉冲幅度谱统计分析及信号到达时间统计。利用 LSO 探测器和 LaBr3：Ce 探测器开展实验，验证了该系统的功能并获得了较好的实验结果。

Abstract：A digital pulsed radiation measurement system is proposed,which uses a digital oscilloscope for data acquisition.The system employs a device control program developed with the aid of VISA technology and object-oriented C++ programming technology applicable for various types of digital oscilloscopes to automatically control the measurement of the sig-nals output from the detector,the storage and backup of the original measurement data,and the statistics of the pulse height spectrum and arrival time of the signals.The system has been tested with an LSO detector and a LaBr3 :Ce detector,and the experimental results indi-cate the system functions well.
