【摘要】 利用5MeV的电子束照射漂移室,在Ar/CO₂,Ar/CH₄及Ar/iC₄H₁₀等不同气体混合物条件下研究了漂移室的暗电流,输出脉冲幅度,能量分辨及计数率坪曲线随单位长度阳极丝上所收集到的总电荷数的变化.更多还原

【Abstract】 The degradation of some performances of the drift chambers irradiated with 5 MeV electron beam has been tested. The gas mixtures filled were Ar/CO₂, Ar/CH₄ and Ar/iC₄H₁₀ in proportion.The dark current, the pulse height, the energy resolution and the counting rate plateau have been measured during the irradiation.更多还原
