摘要

中国科学院高能物理研究所试验束粒子描迹仪系统用三个多丝正比室（MWPC）做探测器描绘粒子飞行的径迹。本文分析了 MWPC 输出信号的特点

介绍 MWPC 阳极信号的前端触发（Trigger）电路及符合电路的原理、设计

并用该电路做触发得到 MWPC 的空间分辨。符合单元按照核仪器标准设计可作为标准核仪器模块（NIM 插件）使用

对 3 个 MWPC 的阳极 Trigger 信号做符合运算

输出的 NIM 电平提供给数据采集系统做门控（GATE）信号。

Abstract

A particle track system was constructed in IHEP to trace the particle’s flight path. Three multi-wire pro- portional chambers (MWPC) were used as detectors in it. This article describes the principle

design and experiments of the trigger circuit for multi-wire proportional chamber ( MWPC) and the coincidence unit. Furthermore

the posi- tion resolution is analyzed.
