“…Similarly for the double-gap RPC using parallel neutron source for GEANT4 standard electromagnetic packages the neutron sensitivity sn < 6.368 × 10 −3 has been noted for En ≈ 1 geV whereas the RPC neutron sensitivity, sn < 6.496 × 10 −3 for the same neutron source, and energies has been obtained using the GEANT4 low electromagnetic packages. The present GEANT4 neutron simulation results are reliable and are in agreement with the experimental results reported in [17,22,23]. A comparison between the simulated and available experimental neutron sensitivity results at low energies can be seen in table 2.…”

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 cm 2 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.

The low rate capability behavior of conventional glass with resistivity ∼ 10 13 Ωcm, is not acceptable in many experiments being performed in high energy physics. The usage of low bulk resistivity glass electrode in the configuration of Resistive Plate Chamber (RPC) makes it possible for such studies where high rate environment is required. The sensitivity to neutron of low-resistive glass electrode RPC has been simulated using GEANT4 Monte Carlo codes with G4 Standard and G4 Low packages. The detailed simulation studies have been performed as a function of neutron energy in the range 10 −10 MeV-10 GeV. The response of the detector in LHC background environment expected in the CMS-barrel region is evaluated for the neutron energy spectrum. According to our obtained results a hit rate 0.532 Hz/cm 2 has been estimated for the RPC located in RB1 station. A comparison of the simulated results with the available experimental results has also been performed.
