Abstract: | In this study the performance of double gap RPC has been tested by GEANT4 Monte Carlo simulation code. The detector response
calculations taken as a function of the neutron energy in the range of 0.01 eV-1 GeV have been simulated through RPC set-up.
In order to evaluate the response of detector in the LHC background environment, the neutron spectrum expected in the CMS
muon endcap and barrel region were taken into account. A hit rate of about 165.5 Hz cm−2, 34 Hz cm−2, 33.6 Hz cm−2, and 27.0 Hz cm−2 due to an isotropic neutron source is calculated using GEANT4 standard electromagnetic package for a 20 × 20 cm2 RPC in the ME1, ME2, ME3 and ME4, respectively. While for the same neutron source and using GEANT4 package a hit rate of
about 0.42 Hz cm−2, 0.7182 Hz cm−2 was measured for the MB1 and MB4 stations respectively. Similar characteristics of hit rates have been observed for GEANT4
low electromagnetic package.
