Neutropn source

Post by theapower » Sat Apr 03, 2021 9:23 pm

My science background is in cell biology with practical skills in tissue culture and microscopy.
After retiring I became friends with an indigenous community in the Chilean Andes and realized what an enormous disadvantage it is having no electricity – this applies to over 1 billion people worldwide. As a result I have designed on produced a small wind generator that will supply the basics of safe lighting, communication, power tools. However, wind cannot power an industrial economy so I switched to the design of a portable thorium-fuelled molten salt reactor. Thorium fusion requires a source of neutrons so I am interested to know whether fusors could be used for this. Any help much appreciated. I live in North East England

Fusors generate no usable energy under any circumstances.

I have been asked to submit my real name rather than the name under which originally registered (ThEA Power). This is:
John David Simnett
Thanks

Why you do not use the traditional methods: such as extracted Radium(226) from Uranium ore and Beryllium(9) scavanged from microwave magnetron. Radium(226) decays by releasing He(4). He(4)+Be(9)>C(12)+n. As to how you should arrange the elements to react in such a way to release the neutron and smash it into Thorium, I'm not sure. Another method is by using 15MeV x rays and smash atoms. High energetically x rays are able to remove neutrons from atoms.

The area circled in red needs to be changed to your real name.

Thanks in advance

We are not allowed to use radium in the U.S. by law or to extract it from Uranium. Even if allowed, the amount of radium needed would produce horrid and dangerous levels of Gamma radiation. It is why no one uses it as a neutron source any more.

I find that quite fascinating. Could you provide a reference for the claim that it's possible to create a RaBe neutron source using ceramic insulators from microwave ovens? It is my understanding that those ceramic insulators are BeO rather than metallic Be. Is there literature documenting successful experiments using BeO to build a neutron source using an alpha emitter and the (alpha, n) reaction?

It appears the amount of Ra-226 in ore is small and barely worth extracting/purifying, so would it not be more practical to use Am-241 from smoke detectors or Po-210 from anti-static brushes as alpha emitters instead? These are widely commercially available.

My apologies if these are trivial or dumb questions, I have a background in electrical engineering and I'm very new to nuclear physics.

We do not make nor support the making of radio-isotope neutron sources here! They are illegal to own without an NRC license. Our fusors are our source of neutrons.

As a theoretical discussion, the world nuclear science community is pretty much using only Am241-Be sources in labs and institutions who need a small permanent neutron source. They must all obtain an NRC license to obtain, store and use one! Yes! Any Be chemical compound will work at grossly reduced efficiency compared to the metal.
The reasons for this one source supplanting all the rest is that it is very easily shielded. It will, effectively, last longer than any institution using it. (No need to ever replace it.)
All significantly useful neutron sources pose a severe environmental hazard. This is why licensing and verifiable stewardship are demanded by the NRC.
Fusors can be turned on and off with none of the environmental issues found in permanent sources. Fusors never put out the neutron numbers found in a permanent source. (Very weak source of neutrons and of extremely low duty cycle in doing so.)
