SELF-QUENCHED GAS-DISCHARGE GEIGER-MULLER COUNTER

摘要

recording beta- and gamma-rays. SUBSTANCE: main gas used in counter is helium held at pressure of 150 to 760 mm of mercury and its quenching additive is mixture of xenon and oxygen, pressure of each of these additives making up 1-5% of helium pressure and xenon-to-oxygen partial-pressure ratio ranging between 0.75 and 1. EFFECT: enlarged operating temperature range and range of intensive rays monitored. 1 tbl
