Abstract
We present a method for the evaluation of the charge collection time in an ionization fission chamber with flat electrodes. The mean charge and the time of its collection are determined according to the parameters of electric signals recorded at the output of the measuring system. We use a model of formation of current pulse in the detector and a mathematical model of measuring circuit. The procedure of finding the charge collection time and the mean charge per pulse is approved in experiments with KNT-34-type ionization fission chambers. Various possibilities of practical application of the proposed procedure are considered.
