Abstract
1,227,515. Discharge tubes. COMMISSARIAT A L'ENERGIE ATOMIQUE. 12 Feb., 1969 [26 Feb., 1968], No. 7486/69. Addition to 1,089,018. Heading H1D. A spark chamber detector as described in the parent Specification comprising a cathode 2, anode 6 and intermediate wide-meshed grid electrode 4, has a filling of xenon and diethylamine. The sum of the partial pressures of the gases is about 760 torr., the partial pressure of diethylamine being preferably from 8 to 50 torr.
