CMS合作计划为非常前沿的μ子系统配备三个GEM探测器，可以承受高亮度LHC的环境。该项目正处于研发和投产的最后阶段。一个前所未有的大面积的几个100平方米的仪器与GEM探测器将在世界各地的六个不同的网站。需要一个共同的结构和质量控制程序，以确保每个探测器的性能。质量控制步骤将包括光学检查、用于构建检测器的所有材料和部件的清洁和烘烤、GEM箔的泄漏电流测试、高压测试、腔室的气体泄漏测试和监测压降与时间的关系、增益校准以了解检测器的最佳操作区域、增益均匀性测试以及研究效率，噪声和跟踪性能的探测器在一个宇宙的立场，使用放大器。
The CMS Collaboration plans to equip the very forward muon system with triple-GEM detectors that can withstand the environment of the High-Luminosity LHC. This project is at the final stages of R&D and moving to production. An unprecedented large area of several 100 m 2 are to be instrumented with GEM detectors which will be produced in six different sites around the world. A common construction and quality control procedure is required to ensure the performance of each detector. The quality control steps will include optical inspection, cleaning and baking of all materials and parts used to build the detector, leakage current tests of the GEM foils, high voltage tests, gas leak tests of the chambers and monitoring pressure drop vs. time, gain calibration to know the optimal operation region of the detector, gain uniformity tests, and studying the efficiency, noise and tracking performance of the detectors in a cosmic stand using scintillators.
