In the framework of the High-Luminosity Large Hadron Collider project (HL-LHC), the LHC experiments will require upgrades to their detectors to cope with the new accelerator performance. The upgrade of the CMS Muon Spectrometer foresees the installation of three new muon stations based on the Gas Electron Multiplier (GEM) technology, referred to as GE1/1, GE2/1 and ME0 detectors. While the installation and commissioning of the GE1/1 detectors is currently underway, the GE2/1 and ME0 detectors are expected to be installed between 2023 and 2027. The CMS Muon Collaboration has developed a novel construction design of large-area, trapezoidal-shaped GE1/1 triple-GEM detectors; in particular, a new self-stretching technique has been introduced to mechanically stretch the GEM-foils without using spacer grids or glue inside the gas volume in order to avoid dead regions (several percent) or possibly outgassing contaminants which could trigger premature aging pr...

CMS-ME0检测器的新型三重GEM机械设计及其初步性能

在高光度大型强子对撞机项目(HL-LHC)的框架内,大型强子对撞机实验将需要升级其探测器,以应对新的加速器性能。CMS Muon光谱仪的升级预计将基于气体电子倍增器(GEM)技术安装三个新的μon站,分别称为GE1 / 1,GE2 / 1和ME0检测器。虽然目前正在进行GE1 / 1探测器的安装和调试,但预计将在2023年至2027年之间安装GE2 / 1和ME0探测器。CMS Muon Collaboration合作开发了一种新颖的大面积梯形形状结构设计GE1 / 1三重GEM检测器; 尤其是,
