Description
Resistive Plate Chambers (RPCs) are widely used in high-energy physics experiments because of their excellent ability to cover large detection areas with high particle detection efficiency and good time resolution. Often these properties are achieved by RPC detectors when they are operated with Freon-based gaseous mixtures that cause high global warming potential (GWP). Therefore, in order to take care of the environmental issues and various restrictions it is imperative to obtain an alternative gaseous mixture that is comparatively environment friendly and yet does not compromise on the performance of RPCs.
The present study is aimed at investigating the effect of using a CO2-based gas mixtures in an glass-based RPC detector compared to the standard C2H2F4/i-C4H10/SF6 gas mixture. The performance parameters of the RPC detectors, such as dark current, count rate, and efficiency, have been obtained and compared when the RPC has been operated at different fractions for these two different mixtures, i.e. the CO2 based and the standard gas mixtures. The data for our study has been collected with cosmic rays utilizing HARDROC-based front-end electronics.
