摘要
本文报告了最小电离β粒子在气体计数管中形成的正比、饱和正比和SQS信号谱,指出了用SQS模式代替传统的正比模式气体取样簇射计数器以改善其能量分辨率的可能性。对SQS的死时间、死空间测量的结果表明,虽然它们对不同的气体成分数值有所不同,但数量级相似,典型值为死时间～10μs,死空间～3mm。
The charge spectra of the proportional, saturated proportional and SQS signals produced by the minimum ionizing β particles in the gas counter are presented. It is pointed out that using the SQS mode instead of the traditional proportional mode as the sampling means in gas sampling shower counter is a promising way to improve the energy resolution. The measured results of SQS dead time and dead space, vary with different gas mixtures, but they are in the same order of maguitude and the typical values are～10μs for dead time and～3 mm for dead space.
