After looking over the patent for the ion pumps on Bert's site, it looks like that would be great for those who only have a roughing pump (even a hand-held $30 auto-parts pump), because you'll have the high voltage supply anyways.
And with a gas like helium (or hydrogen, if your very, very, sure all the O2 is out) a lower ionization potential will make it possible, I think, to power up the fusor, heating and thinning the helium (or H2/D2) to the point where the ion pump can expell it into some charcoal.
Any thoughts or experience with these?
