Abstract : Boron trifluoride is used as the filling gas in ionization chambers and in proportional counters used for counting neutrons. The predominant reaction in these chambers is the (n-alpha) reaction on B(10) with thermal neutrons. Since the performance of counters filled with BF3 is strongly dependent on the quality of the gas, an understanding of this dependence is helpful. While this subject is by no means completely understood, the following discussion summarizes some general information pertinent to this question.
