Description
The CMS detector is being upgraded for the High-Luminosity LHC (HL-LHC) run to begin in 2030. As part of the upgrade, the forward muon system is being strengthened with Gas Electron Multiplier (GEM) detectors to ensure robust performance in high-luminosity and high-background conditions in the forward region of the CMS detector. The experiment has installed 4 wheels each containing 36 chambers as part of the GE1/1 stations, covering 1.55 < | η | < 2.18, and is operational since 2023, delivering excellent efficiency and stability. The GE2/1 station, consisting of 36 chambers or 288 modules, partially installed during recent technical stops, will further extend the coverage and granularity in the forward region 1.62 < |η| < 2.43. It will be mounted during the year-end technical stop after 2030. The ME0 station is planned for installation during Long Shutdown 3 (2026-2029) to extend the muon system’s pseudo rapidity coverage to |η| ≈ 2.8. The ME0 system will consist of 36 stacks of 6 modules each. With six layers of triple-GEM detectors per stack, ME0 is designed to handle intense backgrounds during the HL-LHC run while significantly improving tracking and triggering performance. This talk presents the overall status of the GEM upgrade and highlights the performance of GE1/1.
