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.
