Abstract
Simulation of gamma-ray semiconductor detector generally makes assumpt ions such as electric field uniformity, constancy of mobilities and tr apping times respect to electric field, etc. At least a part of these assumptions are not valid. A way to overcome this problem is to measur e the collection efficiency as a function of depth directly. By a part icular version of the micro-IBIC technique we measured the collection efficiency on a section of a CdTe detector and we used the experimenta l data as input for the Monte Carlo code ISIDE for simulating pulse he ight spectra produced by Co-57. The results obtained by this more real istic approach are presented and can be compared both with other kinds of simulations and with available experimental data.
