| 英文摘要 | This paper presents experimental results of rpcs performances with different working gas mixtures. owing to freon's high global warming potential, its threat to rpcs aging and its large consumption in large particle physics experiments, studies to minimize the concentration of hfc-134a, and even its complete replacement, have been undertaken. in addition, the reduction of iso-butane is also a favorable strategy, due to the flammability level of the gas mixture. freon-less working gas mixture of ar/hfc-134a/i-c4h10/co2=20/0/8/72 was chosen with plateau efficiency of 86.3% and noise rate of 0.61 hz/cm(2). for working gas with lower ratio of freon, ar/hfc-134a/i-c4h10/co2=20/20/8/52 was suggested with plateau efficiency of 91.0% and noise rate of 0.19 hz/cm(2), in which freon was decreased by 22% compared to the besiii rpc gas mixture. furthermore, iso-butane was decreased to 6% with rpc's efficiency of 90% and noise rate of 0.20 hz/cm(2) achieved. finally, the explanation of rpc's different performances at various working gas mixtures has been validated by the investigation of secondary streamers. this study will be helpful for rpc's application in future large particle physics experiments, in which rpcs can run in streamer mode. |
