As it stands we would contine to gain neutron numbers all the way up to 250,000 volts on our little D-D fusors and even at that huge voltage be behind the 30kv applied D-T fusor by a factor of 80!

I'm wondering if it's worthwhile to say Lithium.
Jim posted a 20-30 Barn thermal neutron cross-section for Li(6?) a while ago - It seems
like we could plunk a little glob of LiD or LiH
at the edge of a fusor and form a handy Li ion gun to get some lithium floating around in the chamber, being accelerated just like the Deuterons. That would place some Lithium atoms
in the area of highest neutron flux (the center) during Fusor operation. How much extra tritium (and neutrons for the Li(7) reaction) would this make?
Is LiD a controlled substance?
Also, if you put a nice thick, heavy, tamper around the fusor to keep the neutrons inside, the neutron flux could be increased substantially in the chamber for higher probability of Li+n reactions.
