“…During the investigation of the effect of the variation of bromine partial pressure with noble gas pressure and of temperature on pla~eau characteristics some new observations were made, in particular oscillations of a different character from those already reported by Le Croissette and Yarwood (1951) and van Zoonan and Prast (1952 Uhlig (1948) gives the former as moderately resistant and the latter as of good resistance to bromine at temperatures up to 100 °0. Thin nickel strip of 99· 4 per cent.…”

“…Halogen-quenched Geiger tubes have been investigated by numerous workers (Liebson and Friedman 1948;Le Croissette and Yarwood 1951;Loosemore and Sharpe 1951;van Zoonan and Prast 1952;and Ward and Krumbien 1955) but little information is available concerning their behaviour at elevated temperatures,except that recently reported by Clark (1955). Fujioka, Kita, and Minakawa (1951) have observed, as have Belin and Bainbridge (unpublished data), that alcohol-argon Geiger tubes, with suitable pretreatment, can be made to operate with negligible change in their characteristics to 200 0Q •.…”

SummaryA number of Geiger tubes were constructed using 18: 8 low-carbon stainless steel and 99· 9 + per cent_ aluminium cathode!! with tungsten anodes.Plateaux improved, but threshold voltages rose 2 V /°0 with increase in temperature. Tubes with stainless steel (lathodes operated at 100 °0 for one week showed no deterioration.A few tubes with bromine pressures approximately 0·01 em Hg in a total filling -of ·20 em Hg argon exhibited oscillations over an interval along the length of the plateau. During this interval the tubes were insensitive to external radiations. These tubes, as well as others with higher bromine pressures, also gave, at some defined overvoltage, Geiger pulses with extended tails, upon which 25 kc/s oscillations were superimposed.

Measurements have been. made of the gas amplification factor of a cylindrical counter filled with neon-bromin e and argon-bromin~mixtures. Information has been obtained as to ttie mechanism of gas multiplication when the gas amplification is less than 100. The transit time of electrons across a tube of average dimensions aperated in the proportional region was found to be less then 0.2 microseconds. The duration and the mechanism of the discharge build-up w.as found to change with the amount of bromine present in the counter. w 2. Apparatus. As with previous mcasuramentsr observations have been made on the pulse wMeh,.was,pro6uced when ionizing *) This work Was performed at the Physics Departmeh~ Southamptdn Unive~ity Englai~d.
