The CMS ME0 GEM detector for the HL-LHC / De Bruyn, Isabelle Helena J (Brussels U.) /CMS Collaboration
The CMS Muon system is undergoing significant upgrades for High-Luminosity LHC operation, including the installation of the ME0 GEM detector. This detector is a 6-layer station that will expand the geometrical acceptance for muons up to pseudorapidity $\lvert\eta\rvert=2.8$. [...]
