Gammasphere's detectors use high purity germanium in order to increase a detector's probability of gamma-ray interaction. BGO (Bismuth Germanate) detectors surround each Ge Detector in Gammasphere to help with Compton scattering suppression. They form a hexagonal shape around the cylindrical Ge, and have an additional BGO "backplug", meaning each detector has 7 BGO contacts. Each detector produces ten different signals for the DAQ system known as the GeCenter, GeSide and 7 BGO signals, which are compacted by the analog pre-processing into four differential signals (GeCenter, GeSide, BGOSum & BGOPattern).
