Gamma detector BEGe

• Energy range from 3 keV to 3 MeV combines the spectral advantages of Low Energy and Coaxial HPGe detectors • Detection efficiencies and energy resolutions are optimized in the 3 keV to 662 keV energy region where most tightly-grouped gamma lines of interest are located • Flat, non-bulletized crystals offer optimum efficiencies for samples counted close to the detector • Thin, stable entrance window allows the detector to be stored warm with no fear of low energy efficiency loss over time • Equipped with Intelligent Preamplifier • USB 2.0 Serial Interface The Mirion Broad Energy Ge (BEGe) Detector covers the energy range of 3 keV to 3 MeV like no other. The resolution at low energies is equivalent to that of our Low Energy Ge (LEGe™) Detector and the resolution at high energy is comparable to that of good quality coaxial (SEGe™) detectors. Most importantly the BEGe detector 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 figures below comparing absolute detector efficiencies of a 5000 mm² and 6500 mm² BEGe Detector to coaxial detectors with approximately 60% relative efficiency.
