The saturation curve has been studied in Freon 13-B1 (CF3Br) and in mixtures of Freon with xenon and krypton up to a pressure of 8 atm. The enhanced initial recombination due to the electron affinity of Freon has been evaluated and an empirical formula constructed that describes the fraction of current which escapes initial recombination over a wide range of voltages, pressures, and electrode spacings. After correction for this initial recombination, the general saturation curve for Freon and for mixtures of this gas with krypton and xenon has been derived and, again, convenient empirical formulae established which allow the current collection efficiency to be calculated for any given parameters within the range investigated. These formulae are of practical value in the design of image-forming ionization chambers.
已经对氟利昂13 - B1（CF₃Br）以及氟利昂与氙和氪的混合物在高达8个大气压的压力下的饱和曲线进行了研究。评估了由于氟利昂的电子亲和性导致的增强的初始复合，并构建了一个经验公式，该公式描述了在很宽的电压、压力和电极间距范围内逃脱初始复合的电流分数。在对这种初始复合进行校正之后，得出了氟利昂以及该气体与氪和氙的混合物的一般饱和曲线，并且再次建立了方便的经验公式，这些公式允许针对所研究范围内的任何给定参数计算电流收集效率。这些公式在成像电离室的设计中具有实际价值。
