Über die Ausbreitungsgeschwindigkeit der Entladung in selbstlöschenden Auslösezählrohren

Abstract

The velocityv of the propagation of discharge along the anode of a self-quenchingG—M-counter is a function of total pressureP, pressure of the quenching gasP _D, radius of the cathoder _a and of the anoder _i andV _ü the difference between working- and starting-potential.

For the mixtures argon-methylal, argon-alcohol and helium-alcohol isv=v ₀·exp[k·(V _ü/V _e)^1/2] withv ₀ the velocity at the starting potentialV _e v ₀=(a+b·P _D/P)·V ^1/2_n ·exp [(c−d·P_D/P·V ^−1/2_n ] andV _n=V _e·(lnr _a/r _i)⁻1.k, a, b, c andd are characteristical constants of the filling gas.
