Resistive Plate Chambers (RPCs) play a vital role in high-energy physics experiments, offering excellent particle detection efficiency and time resolution across large areas. Usually, Freon-based gas mixtures facilitate these performance attributes but pose significant environmental concerns due to their high Global Warming Potential (GWP). In light of growing ecological awareness and stricter regulations, this study investigates eco-friendly alternatives aimed at preserving the performance standards of RPCs. We present an evaluation of a glass-based RPC detector utilizing CO \(_2\) -based gas mixtures as a substitute for traditional C \(_2\) H \(_2\) F \(_4\) /i-C \(_4\) H \(_{10}\) /SF \(_6\) mixtures. Key performance indicators –count rate, dark current, and detection efficiency –were assessed across varying CO \(_2\) concentrations and benchmarked against standard gas compositions.

摘要

Resistive Plate Chambers (RPCs) play a vital role in high-energy physics experiments, offering excellent particle detection efficiency and time resolution across large areas. Usually, Freon-based gas mixtures facilitate these performance attributes but pose significant environmental concerns due to their high Global Warming Potential (GWP). In light of growing ecological awareness and stricter regulations, this study investigates eco-friendly alternatives aimed at preserving the performance standards of RPCs. We present an evaluation of a glass-based RPC detector utilizing CO \(_2\) -based gas mixtures as a substitute for traditional C \(_2\) H \(_2\) F \(_4\) /i-C \(_4\) H \(_{10}\) /SF \(_6\) mixtures. Key performance indicators –count rate, dark current, and detection efficiency –were assessed across varying CO \(_2\) concentrations and benchmarked against standard gas compositions.
