sTGC前端电子学批量测试系统设计与应用

Design and Application of sTGC Front-end Electronics Batch Test System

ATLAS探测器PHASEⅠ升级过程中,将新建NSW探测器用于提高对Muon轨迹的探测效率,从而进一步提高一级触发效率。NSW由768个sTGC探测器模块组成,共计约33万探测通道。中国科学技术大学代表中国合作组承担了全部sTGC前端读出电子学设计和生产任务,开发了用于读出strip信号的s FEB读出板和读出pad与wire信号的pFEB读出板,制定了一套完整的FEB测试方案和测试流程。为了对生产完成的上千块FEB进行批量测试,严格按照sTGC读出系统要求,设计了能够同时测试FEB板704通道的多参数批量测试系统。利用FEB批量测试系统,完成了全部850块pFEB和sFEB板测试,并交付ATLAS合作组安装到了sTGC探测器上。

During the upgrade of ATLAS detector PHASEⅠ,NSW detectors will be built to improve the detection efficiency of Muon trajectories,and this will further improve the L1 trigger efficiency.NSW is composed of 768 sTGC detector modules,with a total of about 330000 channels.University of Science and Technology of China,on behalf of the Chinese cooperation group,has undertaken all the design and production tasks of the sTGC front-end readout electronics,and has developed sFEB for reading strip signals and pFEB for reading pad and wire signals.Analyzing the performance requirements of FEB on the NSW sTGC detector,a complete set of FEB test items and test procedures have been developed.In order to perform batch test on thousands of FEBs completed in production,a set of multi-parameter FEB batch test system was designed.The test system can test 704 channels at the same time and run in strict accordance with the requirements of the sTGC readout system.Using the FEB batch test system,all 850 pFEB and sFEB boards were tested and delivered to the ATLAS cooperation team for installation on the sTGC detector.
