Description
The CMS experiment at CERN is foreseen to receive a substantial upgrade during Long Shutdown-3 (LS3) to handle the large number of pileup events in the High-Luminosity LHC. The objective is to increase the integrated luminosity by a factor of 10 beyond the LHC design value (~10^34 cm⁻² s⁻¹). The CMS just commissioned the Gaseous Electron Multiplier (GEM) detector, namely GE1/1, at the endcap during LS2. GEM detectors represent a new addition to the muon system in CMS, in order to complement the existing systems in the endcap, part of CMS most affected by large radiation doses and high event rates.The CMS GEM detectors are made of three layers, each of which is a 50 μm thick copper-clad polyimide foil. The GEM chambers will provide additional redundancy and measurement points, allowing a better muon track identification and also wider coverage in the very forward region. For Phase-2 Upgrade, CMS has outlined plans for further endcap upgrades, such as GE2/1 and ME0, as part of the LS3 upgrade. For ME0 detectors, the part of the detector assembly is expected to take place at different production sites including Panjab University, India. Besides ME0 assembly, also all QCs will be performed before sending them to CERN for installation. This contribution will describe assembly, quality control checks and corresponding results of the triple GEM detector for the ME0 system.
