Detailed optimization procedure of an HPGe detector using Geant4 toolkit

Presented study describes the optimization method of an HPGe detector through implementation of Geant4 toolkit. The optimized model was verified through comparison with experimentally obtained data using a set of point-like radioactive calibration sources. Acquired results displayed good agreement with the experimental data that falls under an average relative deviation of the order of ~ 2% within the energy range of 53–1836 keV. Additionally, in order to test the validity of the code it was also applied to a different detection equipment where an average relative deviation of the order of ~ 1.8% was achieved within the energy range of 121–1112 keV.
