Effect of Gaseous Impurities in BF3 Proportional Counters

摘要

The effects which SiF4, S02, SF6 have on the plateau and pulse size distribution of a proportional counter were investigated. SiF4 was tested at three pressures;30, 45, and 60 cm. of BF3 and its effect was found to be independent of the counter pressure for the range of values considered.
