A Study of Small Ether‐Argon Geiger‐Müller Counters

摘要

A variety of ether‐argon mixtures were tried in counters with cathodes ranging in diameter from 0.268″ to 0.038″ and with wires ranging in diameter from 2.3 mils to 0.5 mil. The results suggest an optimum relationship between cathode diameter, wire size, and mixture. Good characteristics were obtained with cathodes as small as 0.067″ in diameter. Small probing counters designed on the basis of this relationship are described.
