Paper Abstract

We investigated the response function of a planar Cd(Zn)Te detector designed for measurement of electron energy spectra and experimentally measured the response of Cd(Zn)Te detector to radiation of 90Sr/90Y reference radiation source. The obtained experimental spectra were compared with the spectra simulated by the Monte-Carlo method with Geant4 package. We managed to agree the simulated response with the experimental one using only two fitting parameters: products of mobility and average lifetime for electrons and holes. Thereby determined transport parameters of charge carriers were independently verified through the measurement of the positions of low energy 133Ba photopeaks of a reference gamma-ray source.
