Study of neutron response for two hybrid RPC setups using the GEANT4 MC simulation approach

Abstract: 

The present article describes a detailed neutron simulation study in the energy range 10-10 MeV to 1.0 GeV for two different RPC configurations. The simulation studies were taken by using the GEANT4 MC code. Aluminum was utilized on the GND and readout strips for the (a) Bakelite-based and (b) glass-based RPCs. For the former type of RPC setup the neutron sensitivity for the isotropic source was Sn=2.702×10-2 at En= 1.0 GeV, while for the latter type of RPC, the neutron sensitivity for the same source was evaluated as Sn= 4.049×10-2 at En= 1.0 GeV. These results were further compared with the previous RPC configuration in which copper was used for ground and pickup pads. Additionally Al was employed at (GND+strips) of the phosphate glass RPC setup and compared with the copper-based phosphate glass RPC. Good agreement with sensitivity values was obtained with the current and previous simulation results.
