Some Observations on the Behaviour of Bromine?Quenched Geiger Tubes

“…Oscillations on the tail of a Geiger pulse have been reported pre~ously by Le Croissette and Yarwood (1951) and van Zoonan and Prast (1952). These oscillations were different from those observed by the author in that they appeared just after the dead time and died away to zero as the tail of the Geiger pulse approached the end of the normal recovery time.…”

“…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 Fujioka, Kita, and Minakawa (1951) have observed, as have Belin and Bainbridge (unpublished data), that alcohol-argon Geiger tubes, with suitable pretreatment, can be made to operate with negligible change in their characteristics to 200 0Q •.…”
