Sensitivity of Triple-GEM Detectors for Background Radiation in CMS Experiment

The collider experiments of the modern era produce an extreme environment of radiation fields. It becomes quite challenging to operate the detectors in such an environment as the high-radiation background complicates the particle identification. Particles produced in proton–proton (pp) collisions interact with the beam pipe, shielding and the other detector supporting materials to produce charged hadrons and neutrons along with photons, electrons and positrons. These particles interact with the surrounding material acting as a common background radiation field for the CMS detector. CMS has installed new muon detectors based on Gas Electron Multiplier (GEM) technology at the endcap station 1 $(1.55<|\eta |<2.18)$, called GE1/1. In this study, an estimation of the GE1/1 detector response to background radiation is presented using the FLUKA and GEANT4 frameworks.
