论文摘要
CMS实验的EndCAP MUON系统的GE2/1和ME0站的三次探测器已在测试梁中运行，以测量其效率和空间分辨率，以及高空间分辨率的三重分辨率Triple-Gem Tracker。 GE2/1检测器和原型ME0检测器的生产模块显示出极好的局部效率。带有随机孔扇区化的宝石箔的原型检测器显示，死亡区域显着降低。已经测量了跟踪器的空间分辨率，并发现接近期望值为75μm。
Triple-GEM detectors for the GE2/1 and ME0 stations of the endcap muon system for the Phase-2 upgrade of the CMS Experiment have been operated in a test beam to measure their efficiency and spatial resolution, together with a high spatial resolution triple- GEM tracker. A production module of GE2/1 detectors and a prototype ME0 detector show excellent local efficiency. A prototype detector with GEM foils employing random hole sectorization showed significant reduction of dead areas. The spatial resolution of the tracker has been measured and found close to the expected value of 75 μm.
