基于微机的多参数核谱数据获取与处理系统

Microcomputer-Based Multiparameter Nuclear Spectrum Data Acquisition and Processing Systems

本文描述了两个基于IBM-PC/AT微机的多参数核谱数据获取与处理系统。每个参数作为一个子事件,其标码长度最大为12bits。两个子事件组成一个有效事件(双参数系统),或是2—4个子事件组成一个有效事件(四参数系统)。采用顺序记录型DMA方式进行事件标码记录。已用于6项研究课题,效果良好。

In this paper, two multiparameter nuclear specctrum data acquisition and processing systems are described.Each parameter has a .maximum descriptor length of 12 its, and one event recorded in sequential DMA mode consisits of two parameter (dual-parameter system) or two to four parameters (quad-parameter system) .These systems have been working well in &;x research projects.
