BESⅢ TOF前端读出电子学模块测试控制及分析软件系统的设计

The Design of the software for testing Front End Electronic Modules in BESⅢ TOF

为配合BEPC Ⅱ(Beijing Electron Positron Collider,即北京正负电子对撞机)的改造,目前北京谱仪(Beijing Spectrometer,简称BES)正在进行第三期升级改造工程,称为BESⅢ。改造后的BESⅢ将大幅度提高探测器性能。TOF(Time of Flight),即飞行时间计数器,是BESⅢ的重要子系统,其负责时间和电荷测量的前端电子学读出模块(Front End Electronics Module,简称FEE)要求时间分辨率好于25ps,电荷分辨率好于10bit。为了对FEE模块的性能进行测试,保证工程进度和质量,一个完备的测试控制/分析系统的建立是十分必要的。文章将简要论述其中测试控制及分析软件的设计。

TOF（Time of flight） Detector is an important component in BESIII（Beijing Spectrometer Ⅲ ）, and its FEE（Front End Electronic） module is expected to have a time resolution better than 25ps and charge resolution better than 10 bit. This software is developed to provide a convenient ATE（Automatic Test Environment） which includes all the test items for FEEs. The basic structure and corresponding techniques are included in this essay.
