Re: Tubbs Beam-on-Target Effort [Neuts/Pics/Tips]

Re: First neutrons from worlds smallest Fusor!

If that website was indicative of anything it's indicative of the kind of integrity he holds himself to. I would from this not only question his claims here, but those of his original inception to the neutron club.

I have nothing more to effectively add.

Re: Lockheed

Fusion is wonderful, it makes great neutron sources.

<t>Rich, John,<br/> <br/> Very useful primers, thanks for the commentary. I'll review them when I bring the Therac down to vacuum.<br/> <br/> For now, however, the ion pump in question is on a 6MeV Guide that has been at vacuum, RF baked/processed and with the ion pump happily chugging along for abo...
