Study of a Triple GEM detector for the upgrade in the forward region of the CMS Muon System at the LHC

In the coming years, the LHC will enter its phase of high luminosity. As a result the CMS detector complex will be subjected to a high flux rate of particles in the forward region of the muon spectrometer. The purpose of this work is to study Triple GEM detectors for the upgrade in the 1.6 < |⌘| < 2.4 part of the muon spectrometer in CMS in order to increase the redundancy in this region. The major advantage of this new technology is its high detection efficiency under high rates of radiation fluxes. This work is aimed at modeling the response of a Triple GEM detector, ranging from the simulation of a primary ionization, the electron avalanche process to the formation of the signal on the readout electronics. Certain results of this computations will be confronted with real measurements taken with a Triple GEM prototype.
