Abstract：
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 magnitude and the typical values are ~10 μs for dead time and ~3 mm for dead space.
