Abstract: An ultraviolet sensitive, gaseous discharge detector of the Geiger-Muller type has a low spurious count rate and a prolonged lifetime at elevated temperatures. The gas filling of the detector comprises a gas mixture of neon and argon with a small amount of hydrogen added. The gas mixture of neon and argon substantially determines the breakdown voltage and ionization efficiency characteristics of the gas filling. The essential function of the hydrogen is to rapidly de-excite argon metastable atoms which would otherwise cause excessive spurious discharge counts.
