A novel virtual point detector model has been developed for cylindrical high purity germanium detectors used in gamma-ray spectrometry. The model accurately computes the full energy peak efficiency response of the detectors by replacing the detector with a virtual point detector located at the center of the crystal.
A novel virtual point detector model was developed for cylindrical high purity germanium detectors that are widely used in gamma-ray spectrometry. According to this model, the full energy peak efficiency response of these detectors can be computed by replacing the detector with a virtual point detector located at the center of the detector crystal. In fact, the novel model makes the transfer of the FEP efficiency response from a reference point source to a given point source, both sources being located on a line that passes through the virtual point detector. The model was tested and provided accurate results.
