Abstract

Numerical calculations have been performed to understand the reason for the observed non-uniform response of a Resistive Plate Chamber (RPC) in a few critical regions such as near edge spacers and corners of the device. In this context, the signal from a RPC due to the passage of muons through different regions has been computed. Also, a simulation of RPC timing properties is presented along with the effect of the applied field, gas mixture and geometrical components.
