HPGE Detector GEM – Ortec

P-type Coaxial HPGe Detector GEM for High Performance Gamma Spectroscopy in the Energy Range of ~40 kev and Up. ORTEC offers GEM Series HPGe detectors with relative efficiencies1 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.

The majority of gamma spectroscopy applications such as those found in counting laboratories involve the energy range ~40 keV upward. ORTEC GEM and Profile Series GEM detectors are designed to cover this energy range.

All GEM Series feature:

• efficiencies to 150%, higher on request.
• excellent energy resolution and peak symmetry.
• specified crystal dimensions in profile models.
• smart bias options.
• harsh environment (-he) option.
• low-background carbon fiber endcap options.
• plus preamplifier option for ultra-high-rate applications.
• huge configuration flexibility: poptop, streamline and mechanically cooled options.
