ORTEC Semiconductor Radiation Detectors Short Form Catalog
GAMMA-X (GMX) Detectors
GAMMA-X N-type coaxial HPGe detectors are made for highperformance
gamma spectroscopy in the energy range ~3 keV and
upwards.
These 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 3 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.
Special advantages of GAMMA-X Series:
• Ultra-thin boron ion implanted radiation window allows for
spectroscopy from 3 keV upwards.
• Ideal for Compton Suppression systems.
• Neutron damage resistant; user self-repair neutron damage option.
• Be window supplied with protective cover; Al or carbon fiber window option available at no additional charge.
• Low background carbon fiber endcap options.

GWL Series HPGe Well Detector
ORTEC GWL Series High-Purity Germanium (HPGe) Well
Detectors are a good solution for low level counting of small
samples. The unique ion-implanted detector well has an ultra-thin
dead layer (only 0.3 µm thick), and therefore provides the most
extensive useful energy range (10 keV to 10 MeV). ORTEC Well
Detectors have a “blind hole” with at least 5 mm of active
germanium at the bottom of the hole. This near 4 π geometry
provides the maximum absolute counting efficiency available. The
large well (1.55-cm diameter and 4.0-cm long) accommodates an
extensive range of sample sizes. Like all of ORTEC’s HPGe photon
detectors, the HPGe Well detector may be stored or cycled
repeatedly to room temperature without performance degradation.
GWL Series feature:
• Near 4 π geometry; high absolute counting efficiency for small
samples.
• Spectroscopy from 10 keV to 10 MeV.
• Active Volumes to 400 cc.
• Unique ion-implanted blind well.
• Extra-large well (1.55 x 4.0 cm) standard
