瞬发γ射线谱数据在线采集系统研制

Front-End Electronics and Data Acquisition of Prompt γ Spectra

介绍了爆炸物监测数据在线采集系统的研制情况。设计了NIM标准的前端电子学系统,使用基于PCI总线标准的高速数据采集卡,通过编写控制程序实现了多路α与γ信号的相关谱测量。并介绍了几种典型的应用。

The front-end electronics and data acquisition system is a compact set of NIM and PCI boards with a PC. The system is a part of an explosive inspection system based on the tagged neutrons technique. The front-end electronics processes all detector signals and checks coincidence between any alpha particle detector and any gamma-ray detector controlled by computer. Some typical applications are presented.
