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

During the upgrade of ATLAS detector PHASE I, 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 330 000 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.
