Two topics on the, SQS phenomena in proportional counters are reported. One is. the observation of the SQS transition in pure methane gas under irradiatien of 4.5 keV X-rays. The effect of a small amount of argon on, the SQS transition was investigated with gas mixtures (CH4:Ar) having the mixing ratios such as 100:0, 99.8:0.4, 99.7:0.3, 99.5:0.5. 99: 1, 98:2, 95.5:0.5 and 90:10. The SQS transition was not observed in pure methane gas, although it was observed still in the gas mixture of 99.8:0.2. The other is the measurement of electron drift characteristics with a single-Wire gas counter operated. in the SQS transition regions. The counter. gas. used was a mixture of argon and methane (70:30) in which ethanol vapor was added. From comparison with the proportional mode, the use of the SQS mode is recommended to’ obtain a better time resolution in the application of drift counter.
