Abstract :
The transition to the GM mode in a gas counter has been observed with 5.5 MeV α-rays from 241Am source and a counter using a 30 μm thick anode wire for Q-gas. The pulse height spectra are measured as a function of the applied voltage, from which the gas multiplication curve for Q-gas is derived. The results show that the GM mode jumps from the proportional range.
