Simulation results on a resistive plate chamber for a bakelite thickness of $1mm$ up to $3mm$

The performance of bakelite electrodes with thicknesses of 1, 2, and $3mm$ in a double-gap resistive plate chamber (RPC) have been tested by GEANT-based Monte Carlo simulation. Results show that the thickness of bakelite plays an important role in detecting particle signals. For checking the efficiency of these RPCs, gamma particles in the range $0.01–100MeV$ have been simulated through different bakelite setups. For an isotropic gamma source, a sensitivity $sγ<3.5×10−2$ at $<100MeV$ by a $1mm$ bakelite double-gap RPC has been observed. For the same gamma source with a $2mm$ bakelite RPC, a sensitivity $sγ<4.0×10−2$ at $<100MeV$ has been measured, whereas for $3mm$ bakelite RPC, sensitivity results were $sγ<4.44×10−2$ at $<100MeV$⁠. Similar characteristics of bakelite electrodes have been observed for a parallel gamma source configuration.
