Broad Energy Germanium Detectors (BEGe)
Company : Canberra Industries Inc
UMDC Code : 150126
Most importantly the BEGe has a short, fat shape which greatly enhances the efficiency below 1 MeV for typical sample geometries. This shape is chosen for optimum efficiency for real samples in the energy range that is most important for routine gamma analysis. This is in stark contrast to the traditional relative efficiency measurement – a 60Co point source at 25 cm which is hardly a relevant test condition for real samples. See the adjacent figure comparing detector efficiencies for the extremes of coaxial vs. BEGe geometries each having approximately 50% relative efficiency.
