Abstract
Resistive plate chamber (RPCs) is a parallel plate gaseous detector built using the electrodes of high volume resistivity. Operation and performance of the RPCs mostly depend upon the graphite conductive coating acting as the high voltage provider. Therefore, it is imperative that we study the effect of the surface resistivity of conductive coating of graphite on RPC characteristics and performance in detail. In this report, the effects of surface resistivity of conductive coating on the space dispersion of the induced charge of the three fabricated prototype RPCs of surface resistivity 1 M\(\Omega / \Box \), 100 k\(\Omega / \Box \), 40 k\(\Omega / \Box \) have been studied experimentally. All the three RPCs have been studied in avalanche mode of operation.
