使用Ar+CH_4混合气体使漂移室运转,研究了氮、氧及空气杂质含量对漂移室的输出脉冲幅度、能量分解率、计数率及计数率坪阈电压的影响,对几种不同输气管道材料的渗透效应也进行了比较。
The effect of nitrogen, oxygen and air impurities on the output pulse amplitude, energy decomposition rate, counting rate and count rate threshold voltage of the drift chamber was studied by using Ar + CH_4 mixed gas, The material’s penetration effect is also compared.
