HPGe (High-purity germanium) system

The laboratory-based hyper-pure germanium (HPGe) detector is a p-type, 45% relative efficiency, 2 keV FWHM resolution at 1.33 MeV Canberra detector system. The HPGe detector is customized for measuring low-activity samples. The system is placed in a low-background environment by surrounding the detector crystal with 10 cm thick lead castle. The castle has thin copper lining inside to attenuate the low-energy X-rays introduced by gamma-rays mainly in lead. Standard nuclear electronics are used to process the detector signals.
