Advantages

In comparison to other neutron sources our neutron generators offer solid and important advantages

 

This sketch shows how our line source neutron generator can replace two or more point sources in a typical conveyor belt application for online prompt gamma neutron activation analysis.

The maximum total neutron output may be reduced; thus reducing the shielding requirement.

The line source enables a more uniform irradiation of the target material. A "wall source" is also available.

After 2.5 years (22,000 hours) the 252Cf neutron source will have decayed to about half of its original activity. Replacement and safe reprocessing or top-up servicing will be necessary.

The NSD GRADEL FUSION line source neutron generator will still be running at the original neutron output rate. The plasma-gas target is continuously renewed. Other neutron generators, which have solid target technology, will have been renewed at least five times in the same time-frame.

Experience with the Mk0 development neutron generator which was operated for 7,000 hours, before the order to switch it off, gives us the confidence to offer such long life.

 

Advantages:

  • Line source geometry
  • Short electrode point source geometry configuration optional
  • Higher specific output in the most compact form (at least 10 times more output than other compact NGs)
  • Longest lifetime because there is no solid target to erode
  • No accelerated aging of the target due to frequent thermal cycles (there is no solid target!)
  • Pulsed or non-pulsed options
  • Submersible version available
  • Uniform neutron flux field to cross conveyor belt width
  • Multi-chamber configuration options for uniform wall source or versatile source location
  • Only one neutron generator set needed
  • Lower source strength may save shielding cost
  • Versatile system design options
  • Constant, very stable, very low fluctuating and repeatable neutron output
  • Far superior life time endurance compared with other neutron generators
  • NSD GRADEL FUSION life cycle economics fully competitive
