“…In data, the various radii are obtained by using the hit rate for a single 𝜂 partition and plotting at the average radius, and will, therefore, actually be an average over the radial range of the 𝜂 partition. The data show reasonable agreement with the expected background rate based on previous simulation work [4], and are consistent with newer simulation produced after the data collection period [10].…”

The Phase-II high luminosity upgrade to the Large Hadron Collider (LHC) is planned for 2023, significantly increasing the collision rate and therefore the background rate, particularly in the high 𝜂 region. To improve both the tracking and triggering of muons, the Compact Muon Solenoid (CMS) Collaboration plans to install triple-layer Gas Electron Multiplier (GEM) detectors in the CMS muon endcaps. Demonstrator GEM detectors were installed in CMS during 2017 to gain operational experience and perform a preliminary investigation of detector performance. We present the results of triple-GEM detector performance studies performed in situ during normal CMS and LHC operations in 2018. The distribution of cluster size and the efficiency to reconstruct high 𝑝 𝑇 muons in proton-proton collisions are presented as well as the measurement of the environmental background rate to produce hits in the GEM detector.
