WORK FUNCTION OF ELECTRONS AND PROPERTIES OF GEIGER-MUELLER COUNTERS
Otto J. Orient · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1957
An investigation was made of the influence of the work function of electrons from the material of the cathode of self-quenching Geiger-Mueller counters on their parameters. Cathodes of zinc, cadmium, copper, and nickel were investigated. If the filler and the geometry are the same, counters with cathodes having a larger work function have a longer plateau and a smaller slope than counters with cathodes having a smaller work function. In counters with different cathodes, for identical overvoltages, the quantity of electricity per discharge are approximately the same. This indicates that the number of formed ions is independent of the material of the cathode.
