Abstract:

In this study, the optimization of the p-type HPGe detector model has been performed to improve the accuracy of Monte Carlo simulation in calculating full energy peak efficiency. The optimized detector model was validated by comparison of simulated efficiencies with experimental efficiencies for measurement configurations of point-like sources at various distances from the detector surface and cylindrical sources on the detector surface. The obtained results showed an excellent agreement between the simulated and experimental efficiencies with relative deviations of less than 4% in the energy range from 53 to 1847 keV.
