Radiation Detection Company NATS Incorporated Introduces "The HAWK" - The Affordable, Ultra Light High Resolution Germanium Field Gamma Spectrometer

Share Article

The HAWK is field gamma spectrometer based on high purity germanium technology. The HAWK has been designed to bridge the gap in commercially available solutions by offering the customers an affordable solution devoid of the the disadvantages of the more expensive systems in the market.

Commercially available high resolution field Gamma Spectrometers are either too heavy for field use or are priced beyond the budgets of most users interested in such a device. Recent developments in electrically cooled systems while looking impressive still does not effectively solve the needs of a typical User who requires a reliable device at an affordable price, and without the technical problems and failures of complex systems.

There are several observed limitations in some of these newer field gamma spectroscopy systems in the market - let alone cost, weight (or both) and the issues of higher chances of failure of cooling systems.

In addition the low efficiency/sensitivity to neutrons overrides the advertized “benefits” of some “dual detection” systems. In applications where detection of gamma radiation along with neutrons is a requirement (which is a small segment of the market), the neutron sensitivity of the small internal neutron detector used in such Gamma- Neutron detection to advertize this “benefit of dual use” is far too less for all practical uses. The detection sensitivity to neutron in such systems are so poor that using a secondary hand held device using traditional Neutron Survey instruments at a fraction of the cost provides the real solution in such applications where neutron detection is a must.

Evaluation of some of the newer devices reveal other problems. The restrictions in operating time mandates frequent swapping of rechargeable batteries (which by itself requires many hours for charging) nullifies the advantages perceived in “electrical cooling” of such devices. The requirement for swapping of batteries in the field, or charging time for batteries used to power the devices crosses out the perceived advantages of “No LN2 Cooling.” Also electrically cooled systems require several hours of cooling before use. There is no indication that electrically cooling may cool the device faster than liquid nitrogen cooling.

As such the cost of such devices simply because it may be “electrically cooled” or provides symbolic “neutron” detection, may not justify its cost in many applications. And neither offer an User the optimum price to performance ratio for the additional cost.

Unfortunately, these disadvantages are not clear to cursory review of such highly advertized devices which would otherwise nullify any advantages to justify the cost of such new devices in all cases.

To meet the real needs of the greater market without the above problems, and an affordable cost, NATS has introduced the “HAWK.” The Hawk is the world’s smallest liquid nitrogen cooled gamma spectrometer based on HPGE detectors. The hawk is ultra light, portable device, smallest in its family.

The Hawk also provides a complete range of functions and features which are offered by regular Laboratory grade High Purity Germanium detector based Gamma spectroscopy systems. The Hawk provides a digital 16K MCA with full electronics, data acquisition and analysis software and runs off low power batteries. The Hawk has a reduced weight, only a little heavier than a gallon of water. The system uses liquid nitrogen which allows us to guarantee a minimum of 20 hours usage without needing to recharge or hot swap batteries on the crystal cooling system.

The Hawk comes with an LCD touch screen to easily operate and change the device settings. It also provides the ability to use the EFFCAL software to conduct mathematical estimation of various complex field geometries using the Monte Carlo Neutron Transport Code (MCNP) based efficiency modeling.

If you need a common sense field unit that is affordable, ultra light, and operates without the problems inherent in some of the expensive devices; and addresses the real needs in 90% of the applications, then the HAWK is your solution.
