A Data Acquisition System for Position Sensitive Detector

介绍位置灵敏探测器数据采集系统的设计与实现。该系统由两片或三片微通道板、位置读出阳极以及数字化处理系统模块构成，具有较高的数据获取速度和灵活性。在微型计算机的支持下，系统的每个数据获取通道相当于一个微机多道分析器，可以根据实验需要的通道数很方便地组合数据获取通道，特别适用于一维或二维的位置探测。通过对系统性能进行测试，得到了很好的结果。目前，该数据获取系统已经成功地应用于（ｅ，２ｅ）实验。

A data acquisition system designed for position sensitive detectors is presented. It consists of two or three pieces of microchannel plate (MCP), a position reading anode and a digitizing module. Aided by a micro computer, each data acquisition channel of the system is equivalent to a multichannel analyzer. It is convenient to build the system made up of different number of data acquisition channels so as to accomplish one dimensional or two dimensional position detection. It is supposed to have high data acquisition speed and flexibility. The physical result is fairly good by testing the performance of the system. The system has been successfully applied to (e,2e) experiment.
