摘要：
The performance characteristics of a proportional counter filled with a gas mixture of Freon-14 (CF4) and Xe at pressures of 0.8-14.8 atm were measured. Adding some Xe (a 1-2% concentration is optimal) to CF4 was found to approximately halve the operating high voltage needed for achieving the same gas-amplification factor as in pure CF4, improve the energy resolution, and increase the expected ultimate gas-amplification factor by an order of magnitude.
