Description
Resistive Plate Chambers (RPCs) are widely employed in high-energy physics experiments due to their excellent timing and efficiency capabilities. However, the conventional freon-based gas mixtures employed in RPCs contribute significantly to greenhouse gas emissions due to their high Global Warming Potential (GWP). This study examines the performance of a single-gap glass RPC detector (30 cm x 30 cm) with the standard gas mixture (C₂H₂F₄ 95%, i-C₄H₁₀ 4.5%, SF₆ 0.5%) and eco-friendly alternatives based on CO₂ and HFO gases. The detector was tested using cosmic muons, and its performance in terms of efficiency, time resolution, and charge distribution has been evaluated under these gas configurations. The results provide valuable insight into the feasibility of adapting environmentally sustainable gas mixtures without compromising the operational performance of RPC detectors. This study contributes to a larger effort to operate gaseous detectors in particle physics experiments in an environmentally responsible manner.
