摘要: The CMS muon system in the region with 2.03<|η|<2.82 is characterized by a very harsh radiation environment which can generate hit rates up to 144 kHz/cm$^{2}$ and an integrated charge of 8 C/cm$^{2}$ over ten years operation. In order increase detector performance acceptance for physics events including muons, new station (ME0) has been proposed installation that region. technology Triple—Gas Electron Multiplier (Triple-GEM), already qualified operation system. However, additional set studies focused on discharge probability necessary ME0 station, because large mentioned above. A test was carried out 2017 at Cern High energy AcceleRator Mixed (CHARM) facility, aim giving estimation Triple-GEM detectors intense field environment, similar one dedicated standalone Geant4 simulation performed simultaneously, evaluate behavior expected exposed CHARM field. geometry carefully reproduced, as well background present facility. This paper presents results obtained from simulation, terms sensitivity together analysis deposited gaps processes developed inside detector. will be presented, complete discussion obtained, turn consistent measurements other groups.
