摘　　要：介绍了一种基于分离元件设计的应用于多气隙电阻板室探测器信号输出放大及前沿时间甄别的电子学模块,该模块有价格低廉、制作方便、便于快速组装测试系统等优点,并详细阐述了关键电子学参数及噪声控制方案,最后给出了基本性能测试数据。设计的电子学模块配合数据获取系统,可组成粒子飞行时间小型测试系统,应用于多气隙电阻板室探测器样机性能的宇宙射线测试和束流测试工作中。Background： The output current signal of Multi-gap Resistive Plate Chambers （MRPCs） has low amplitude and fast speed. Purpose： Its amplitude and time information should be obtained in particle Time-of-Flight （TOF） detection. Methods： A simple electronics module for the presentation of the signals from MRPCs to standard existing digitization electronics is described. The circuit is based on ＂off-the-shelf＂ discrete components. An optimization of the values of specific components is required to match the aspects of the MRPCs for the given application. The key electronic noise control plan is also discussed. Results： This electronics module has the excellent features including low prices, convenient making, easy assembling for testing system, etc. Conclusions： This electronics module is an attractive option for the front-end signal processing in MRPCs prototyping and bench or beam-testing efforts, as well as in final implementations of small-area particle TOF system with existing data acquisition systems.
