AMETEK Offers Harsh Environment Option for Its HPGe Coaxial Photon Detectors


OAK RIDGE, TN - The ORTEC Products Group of AMETEK Advanced Measurement Technology has
introduced a new option for their ORTEC® Pop-Top GEM and GMX coaxial high-resolution detector
line: a Harsh Environment (HE) detector.

"Development of the HE Detector greatly broadens the range of applications for these versatile
high-resolution detectors, allowing users to take measurements in previously prohibited environments,"
notes Ben Kennedy, Product Manager for Detectors for the ORTEC® Products Group.

"By coupling a corrosion-resistant carbon fiber end cap with an environmentally sealed
electronics chamber, we now are able to deploy high-purity germanium-based (HPGe)-based GEM and
GMX coaxial detectors in otherwise prohibitive environments without reducing spectroscopic
performance," he adds.

The carbon fiber endcap provides a thin radiation entrance window without the additional
radioactive background found in most metal alloys. By sealing the electronics within a heavily anodized
shroud, HPGe detectors now can be used in situations where dirt, dust, and moisture may have
otherwise made their use prohibitive. A replaceable desiccant pack ensures the electronics chamber
stays dry.

ORTEC has more than 40 years of experience in the design and manufacture of highly sensitive
radiation detectors that are used by government and industrial laboratories, nuclear facilities and
medical research and in nuclear safeguards.

ORTEC is one of only two private manufacturers worldwide with the ability to produce
germanium crystals with purity levels high enough to make high-resolution radiation detectors.
