Gamma-Ray Spectrometer suits counting lab applications.
Press Release Summary:
Suited for fixed and mobile counting room applications, LDM-1 laboratory detector module is based on high-purity Germanium detector element that is cooled by miniature cryocooler rather than liquid nitrogen. Detector is encapsulated within cryostat so that there is no need to thermal cycle during partial warm up. Powered by 10–17 Vdc supply, self-contained unit has built-in digital signal processor, as well as built-in battery backup that allows it to run up to 4 hr in event of power failure.

Ametek Introduces Laboratory Detector Module
LDM-1 Is Integrated HPGe Gamma Spectrometer for Laboratory Applications
OAK RIDGE, TN– The ORTEC® Products Group of AMETEK Advanced Measurement Technology (AMT) has introduced the LDM-1, an integrated gamma-ray spectrometer for fixed and mobile counting room applications. The self-contained Laboratory Detector Module (LDM-1) builds upon technologies developed for the ORTEC Detective family of portable nuclide identifiers that are deployed for Homeland Security applications around the world.
“The LDM-1 represents a natural progression for a technology initially developed for Homeland Security but equally applicable for counting lab applications,” says Jeremy Whorton, ORTEC Product Manager.” It is a compact, all-in-one unit that is quiet in operation and that generates very little waste heat (less than 20 watts) making it ideal for small or confined spaces.”
“At the heart of the LDM-1 is a high-purity Germanium (HPGe) detector element that is cooled by a miniature cryocooler rather than conventional liquid nitrogen. The detector is encapsulated within a highly reliability cryostat so that there is no need to thermal cycle during a partial warm up. Miniature Stirling Cycle coolers have proven highly reliable for cooling ORTEC HPGe detectors in the field. Now, in the LDM-1, we have adapted them for use in a laboratory environment,” notes Whorton.
The LDM-1 is powered from a small 10-17V DC supply and has a built-in battery backup that allows it to run up to 4 hours in the event of a power failure. The LDM also has a built-in a high-stability digital signal processor. All that is required for a complete gamma spectrometry system is a power source (AC or DC) and a PC on which to install the accompanying MAESTRO® MCA software.
“The all-in-one configuration of the LDM-1 along with its small laboratory footprint low-power consumption and operational silence make it highly desirable for counting laboratories, where space is often at a premium and energy efficiency a plus,” concludes Whorton.
ORTEC Products Group of AMETEK AMT has over 50 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. It is one of only two manufacturers worldwide with the ability to produce both high-purity germanium and high-resolution radiation detectors from it.
ORTEC also is a leader in systems, digital signal processing electronics and software associated with such applications.
