| Abstract: | This study uses Daya Bay RPCs operating in streamer mode to investigate gas mixtures of at least 50% argon,at most 6% isobutane,and with small amounts of SF6.Isobutane is reduced to 2% without degradation of performance,and SF6 reduces the noise rate and current,as well as the signal size.This study provides quantitative relationships between basic RPC operating parameters and various gas compositions. |
| Keywords: | RPC gas composition streamer isobutane Daya Bay SF6 |
