Sažetak
Gases (propane, isobutane, DME) and their mixtures with argon were studied in strong non-uniform electric fields of a proportional counter. Over-exponential dependence of gas gain on high voltage in mixtures with low partial pressure of admixture was observed. A partial pressure of 10 kPa was determined as a requirement for good quenching property of the mixture. The best energy resolution was measured in intermediate gas gain range for lower admixture concentrations, but at high gas gains R degraded very fast. The Townsend ionisation coefficient alpha/P was determined for all gases and gas mixtures over a wide range of strong reduced electric field strengths. The alpha/P under non-equilibrium conditions was dependent on gas pressure.
