Effect of Electric Field and Gas Mixture on RPC Time Resolution

Abstract

A large number of Resistive Plate Chamber will be used in the ICAL detector set-up in the proposed INO facility. The timing response from RPCs will govern the accuracy of ICAL in distinguishing the up-going muon tracks from the down-going ones by recording the time of passage of the muons through the RPCs. The timing performance of a bakelite RPC has been studied both experimentally and numerically to understand the effect of different operating conditions, like applied voltage and used gas mixture, on the timing properties. This can lead us to judge the suitability of bakelite RPC for application in ICAL set-up which is planned to be equipped with glass RPCs at present.
