The Discharge Mechanism of Self-Quenching G-M Counters
Abstract
A split counter arrangement was used to investigate the absorption coefficients of the radiation which causes the discharge to spread along the wire of a counter after the triggering of a pulse. The counters used were filled with various pressures of methylene bromide and argon, and with ethyl alcohol and argon. The results indicated that the vapor dissipated electron energies thereby reducing the number of photons produced during the discharge. It was also observed that the absorption coefficient was a function of the argon alone, from which it was concluded that photo-ionization of the argon was responsible for spreading the discharge along the wire. This behavior was observed with helium and neon in combination with alcohol or methylene bromide.
