Neutron generator graphite moderation

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

Neutron generator graphite moderation

Post by Sarmad suseyn » Fri Nov 06, 2020 7:20 pm

I had a graphite cube 200mm×200mm so i decided to to make something that gives me neutrons all the time, unless I stop it.
I 3d printed a template for some holes in the graphite block , ordered stainless steel tubes 40mm long 6mm diameter, and filled it with some oxides,🙄
Got my small AmBe source and placed it on top, and covered it with HDPE,
I placed the 42-14 neutron detector near it and connected to ludlum model 2200,
The test time was 1 minute
Got 300 counts with this setup,
Now dont kick my az, Specially you Richard.
i like to do experiments, im doing them so no one will.

Nice little source. I am not sure about Kuwait's nuke regulations, so that is a non-issue here.

Again, impressive work. However, a fusor would provide vastly more neutrons. Still, I'm sure it was a fun learning experience and if it was the 1950's, no doubt others would try it, too ;) .
