基于微机的多参数核物理实验数据获取分析系统

The multiple parameter measuring system based on PC for nuclear physics experiments

介绍一台由微机控制的用 CAMAC插件组成的多参数数据获取和离线数据分析系统。该系统采用软件控制的方法进行信号种类的甄别以及划定信号收集的范围。与用 NIM系统构成的数据获取系统相比 ,在达到同样测量精度的基础上 ,降低了对硬件设备的要求。该系统再配合微型电离室、芪晶体探测器 ,被用来做裂变中子飞行时间谱的测量 。

This paper introduces a new multiple parameter nuclear data acquisition system based on CAMAC controller and software to distinguish different type of the signals and set up the energy windows. In this way, hardware was reduced and accuracy improved. The ratio of the 248 Cm prompt SF neutron to 252 Cf one have been given.
