Über die Ausbreitungsgeschwindigkeit der Entladung in selbstlöschenden Auslösezählrohren
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 gasPD, radius of the cathodera and of the anoderi andVü the difference between working- and starting-potential.For the mixtures argon-methylal, argon-alcohol and helium-alcohol isv=v0·exp[k·(Vü/Ve)1/2] withv0 the velocity at the starting potentialVev0=(a+b·PD/P)·Vn1/2·exp [(c−d·PD/P·Vn−1/2] andVn=Ve·(lnra/ri)−1.k, a, b, c andd are characteristical constants of the filling gas.
