Angular Dependence of Cathodic Induced Signals in a Cylindrical Proportional Detector

摘要

A cylindrical proportional counter with a cathode consisting of eight independent sectors, is used to analyse the pulse height distribution of the induced signals as a function of the polar angle. This distribution is found to be anisotropic, which can in fact be explained assuming that the avalanche does not uniformly surround the anode wire. (Atomindex citation 16:008986)
