GEIGER-MULLER COUNTING TUBE
Patent
·
OSTI ID:4801283
A Geiger-Mueller counting tube was developed. The envelope has closely- spaced wall portions forming a first smaller counting discharge space and widening extensions of the wall portions and integral therewith forming a second larger radiation-receiving space communicating with the first space via an opening located at the junction of the closely-spaced wall portions and widening extensions. The ionized gas filling in the envelope includes at least 0.001% of a halogen-type quench. The cathode and anode electrodes were adapted and arranged to sustain a discharge within only the first smaller space and are located in positions permitting the passage of particles generated substantially anywhere in the second space by incident radiation to the first space between the electrodes to initiate discharges therein, (M.C.G.)
