Abstract
The gas mixture to be used in the RPCs of INO-ICAL experiment is a mixture of R-134a, isobutane and \(\text {SF}_{6}\). Owing to huge Global Warming Potential of this mixture (GWP 1403), this needs to be substituted with an eco-friendly gas mixture without compromising the performance of ICAL. In this work, we propose to study the qualification of a mixture of argon and \(\text {CO}_{2}\) for avalanche mode operation of RPC, which has a very low GWP (\({<}1\)). To estimate the streamer probability of the new gas mixture at different operating voltages, the electronic charge produced in RPC signal has been simulated using two numerical methods.
