DESCRIPTION:Speakers: Giovanni Mocellin ()\nCMS experiment is one of the t
 wo general purpose experiments at the LHC pp collider. For LHC Phase-2\, t
 he instantaneous luminosity delivered to the experiment will reach $5\\tim
 es10^{34}$ cm$^{-2}$s$^{-1}$\, resulting in high particle fluxes that requ
 ires the detectors to be upgraded. The forward regions\, corresponding to 
 the endcaps of the detectors\, are the most affected parts. In the CMS exp
 eriment\, to cope with the higher event rates and larger radiation doses\,
  triple-layer Gas Electron Multipliers (GEM) will be installed in the muon
  endcaps. Triple-GEM chambers will complement the existing Cathode Strip C
 hambers\, leading to a better identification of the muon tracks and a redu
 ction of the trigger rate due to the suppression of fake candidates. In ad
 dition\, the forward coverage will be further extended.\nFor the first dis
 k of the muon endcaps\, 144 GEM chambers are being built in production sit
 es spread in 7 different countries around the world. For the first time\, 
 such detectors will have large sizes of the order of $1$-$2$ m$^2$\, thus 
 high requirements on the uniformity across the detector are needed. Before
  the final installation in the CMS detector\, to test their integrity\, qu
 ality and performance\, the GEM chambers undergo multiple quality control 
 tests.\nThis talk gives an introduction to GEM detectors and presents resu
 lts of the performance tests.\n\nhttps://indico.particle.mephi.ru/event/22
