Abstract: A Geiger-Muller counter tube includes a cylindrical enclosing tube, an anode electrode, a cylindrical cathode electrode, a bead, an inert gas, and a quenching gas. The cylindrical enclosing tube has a sealed space. The anode electrode is disposed inside the space and formed in a rod shape. The cylindrical cathode electrode surrounds a peripheral area of the anode electrode inside the space. The bead is formed of an insulator and having a through-hole in the center, the anode electrode passing through the through-hole. The bead is secured to the anode electrode in a position where the anode electrode is surrounded by the cathode electrode. The inert gas and the quenching gas are sealed inside the space.

Abstract: A Geiger-Mueller ("GM") tube containing a noble gas mixture of about 98-99.9% Ne and the remainder Ar, and in addition containing from 2-5% ethylene as the quench gas, provides high stability and high count rates in the temperature range from about -100.degree. C. to about 200.degree. C. When this GM tube is provided with a sleeve-and-screen liner in electrical contact with an outer cathode, the tube exhibits exceptional sensitivity. The sleeve may be a continuous deposit of a heavy metal having an atomic number from about 73 to about 83, deposited on the inner surface of the cathode tube, or the sleeve may be a foil liner of tungsten or tantalum. The screen is woven of metal wire on which is deposited a heavy metal.

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.
