ORTEC offers GEM Series HPGe detectors with relative efficiencies 1 from 10% to 150% and beyond. The detectors are manufactured from ORTEC-grown germanium crystals processed in our advanced manufacturing facility in Oak Ridge, TN. The detectors are fabricated from P-type germanium with an outer contact of diffused Li and an inner contact of ion-implanted boron. ORTEC maintains a large stocklist of GEM detectors. Some of these have “super specifications,” that is, a warranted energy resolution better than the usual GEM warranted specifications
