Mô tả ngắn:phổ kế gamma có độ phân giải cao nhất thế giới
The HAWK’s innovations address the technical setbacks of failure-prone components, weight, and the high cost of established products in its class. It is an affordable, durable, light-weight high resolution germanium detector-based portable spectrometer offering the best price-to-performance ratio in this class of products. 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. Or the real world use of the expensive tools are obscured by redundant or cursory features that adds at most only symbolic value in real world situations.
Những cải tiến của HAWK giải quyết những thất bại kỹ thuật của các thành phần, trọng lượng, và chi phí cao của các sản phẩm được thành lập trong lớp của HAWK. Đây là máy quang phổ cầm tay có độ phân giải cao, bền và có độ phân giải cao, giá cả phải chăng, cung cấp tỷ lệ giá-hiệu suất tốt nhất trong loại sản phẩm này. Gamma Spectrometers có độ phân giải cao trên thị trường thương mại là quá nặng để sử dụng ngoài hiện trường hoặc có giá vượt quá ngân sách của hầu hết người dùng quan tâm đến một thiết bị như vậy. Hoặc việc sử dụng các công cụ đắt tiền trong thế giới thực bị che khuất bởi các tính năng thừa hoặc cursory chỉ bổ sung nhiều nhất giá trị tượng trưng trong các tình huống thực tế.

Recent developments in electrically cooled systems, while improving aesthetics, do not effectively solve the needs of typical End-Users who require a reliable device at an affordable price, and without the technical hurdles of complex systems.
There are several other critical limitations in newer field gamma spectroscopy systems in the market – cost, weight, and the higher chance of failed cooling systems.
In addition, the low efficiency/sensitivity to neutrons overrides the advertised benefits of “dual detection” systems now offered. In esoteric applications where detection of gamma radiation along with neutrons is a requirement, the neutron sensitivity of the a small internal neutron detector is far too small for practical use. The detection sensitivity to neutrons in such systems are poor and require a secondary hand held device. A traditional Neutron Survey instrument is low cost, reliable, and provides a viable solution in such applications where neutron detection is a requirement.
A closer look at some newer portable HPGe detection systems reveal other concerns. Restrictions in operating time mandates frequent swapping of rechargeable batteries. The recharging process takes hours, nullifying the advantages perceived in electrical cooling. In addition, electrically cooled systems require several hours of cooling before initial use. This start up wait-time can also be problematic, requiring responders to keep the units cooled at all times.
As such the cost of such devices are driven up with mechanical cooling and neutron detection. However, most applications do not need these features.
To meet the market need for a low cost, reliable solution to field HPGe detection, NATS has introduced the HAWK. The Hawk is the world’s smallest high resolution gamma spectrometer based on germanium (HPGE) detectors. The hawk is an ultra light, portable device, with a complete range of functions and features which are typically found in laboratory grade High Purity Germanium detector based gamma spectroscopy systems.
The Hawk includes a digital 16K MCA with full electronics, a data acquisition system and analysis software. The battery powered unit uses a low power draw because it is not powering the mechanical cooler. The Hawk weighs less than 5kg and uses a small liquid nitrogen reservoir which guarantees a minimum of 20 hours of use 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 estimations of various complex field geometries using the Monte Carlo Neutron Transport Code (MCNP) based efficiency modeling.
If you are considering options for HPGe, consider a common sense field unit that is affordable, ultra light, and operates without the problems inherent in some of the expensive devices. We find it addresses the needs in 90% of our customers applications.
