Plenty of experimental studies on the effects of performances of RFC operated with different gas mixtures have been carried out. The curves of signal amplitude, multi-counting, efficiency, single counting rate and dark current versus the high voltage were measured using cosmic rays, based on the gas mixtures of Argon, Iso-butane and F134A with different fractions. The measured results show the plateau length could be prolonged, the detection efficiency increased and the dark current decreased in the plateau...

Plenty of experimental studies on the effects of performances of RFC operated with different gas mixtures have been carried out. The curves of signal amplitude, multi-counting, efficiency, single counting rate and dark current versus the high voltage were measured using cosmic rays, based on the gas mixtures of Argon, Iso-butane and F134A with different fractions. The measured results show the plateau length could be prolonged, the detection efficiency increased and the dark current decreased in the plateau region of RFC, if the Argon ratio was reduced and the ratios of Iso-butane and F134A increased correspondingly, at the cost of increasing the working high voltage.

对不同比分气体对RPC性能的影响进行了大量的实验研究,主要是进行了基于氩、异丁烷和绿色氟利昂F134A(C_2H_2F_4)的实验,保持氩气的比分为20%,30%,40%,改变异丁烷和F134A的比分进行实验,分别测量了探测效率、单计数率、暗电流、信号幅度和多重计数随高压的变化曲线,结果发现,减少氩气的比分,增加异丁烷和F134A的比分可以增加RPC的坪长,探测效率也有所提高,在效率坪区的暗电流也有所减小,但工作高压也需要相应地增加。
