Simple direct accelerator, using Pd as a deuterium source

Although I want to eventually build a fusion-capable device, I don't have the space or funding for a full sized fusor. I have come up with this idea for a relatively simple (if unoriginal) design and wanted to get some feedback on whether or not this would be capable of fusion. The gist of it is to ...

Re: Review article on beam/accelerator driven fusion?

Most reactions have no data at low energies because the output would be so tremendously low. Fusion is a tunneling process so it depends on particle energy and the width of the potential barrier. For example, proton-proton fusion could technically take place in water but the probability of this occu...

Re: New neutron detector available

Very interesting. How would you say it compares to a bubble detector in terms of sensitivity and only detecting neutrons?

Re: Review article on beam/accelerator driven fusion?

I use this, shown to me by someone on this forum a little while back: https://www-nds.iaea.org/exfor/endf.htm It's not perfect but it's the best I've seen so far. You can search for a given reaction (say for the 700 kV Cockcroft and Walton experiment you mentioned, you would do Target: Li-7, Reactio...

Re: Power Supply for a Boron based Russian Neutron detector

That flyswatter Geiger tube supply is very interesting, I think I'm going to order one and try it out for myself. Thanks for the tip! Have you tried it with one of the surplus cheap neutron tubes (B10 or He3) on Ebay? I feel like it probably wouldn't work at detecting solely neutrons given the issue...

Re: Constant Neutron Source

What exactly do you mean? If your fusor is fusing deuterium, then it will be producing fast neutrons. Almost all of them will easily pass through the fusor walls, so you don't even need a special frame design in order to get detectable neutrons escaping. If you are just asking for help on building t...

Re: Sources of pyroelectric crystal (LiTaO3 and LiNbO3)

Thanks for the help Allen. It's my understanding that even if the crystal is not Z-cut, there will still be a Z face, it just will be very small if the crystal is a flat slide (for example in the SAW crystal from the Rapp Instruments page he used the thin edge of a SAW crystal as his Z face for the ...

Sources of pyroelectric crystal (LiTaO3 and LiNbO3)

I hope this is the right section for this. I've seen this subject discussed here before but it was on a completed project page. I was wondering if anyone had any good sources of the small pyroelectric crystals LiTaO3 or LiNbO3 that aren't the very expensive $700 giant crystals you can buy from suppl...

Interesting cellphone based radiation detector

I wanted to share this interesting application I tested out earlier this fall. It's an Android (and I assume iOS but I haven't looked) app that allows you to detect gamma (and probably higher energy beta) radiation using the phone's camera. https://play.google.com/store/apps/details?id=com.rdklein.r...

Re: Spellman DXM70N600X3547 power supplies on ebay -70kV 8.5

Damn that's a good deal. Shame I can't justify the cost at this point. Congratulations to anyone that picks one of these up.
