GMX N-type Coaxial HPGe Detectors
GAMMA-X N-type coaxial HPGe detectors for gamma spectroscopy down to 5 keV.
GAMMA-X (GMX) detectors are coaxial Germanium (Ge) detectors with an ultra-thin entrance window. While most coaxial detectors have entrance windows from 500- to 1000-μm thick, the entrance window of these detectors is a 0.3-μm-thick, ion-implanted contact, extending the lower range of useful energies to around 5 keV. Ion implantation results in a totally stable contact which will not deteriorate with repeated cycling. Moreover, N-type HPGe detectors have been shown to be resistant to damage by fast neutrons.
GAMMA-X Series feature:

- Thin boron ion implanted radiation window, ideal for Compton suppression systems.
- Neutron damage resistant; user self-repair neutron damage option.
- Excellent energy resolution and peak symmetry.
- SMART bias options.
- Al or carbon fiber window.
- Low background carbon fiber endcap options.
- PLUS preamplifier option for ultra-high-rate applications.
- Configuration flexibility.
