Some new topologies have been investigated by most all fusor groups. The spiral inner grid sounds interesting. Deuterons are never emitter by the grids. They are formed any whwere in the chamber where there are energetic electrons. Concentrate the electron emission and you concentrate, quite nearby, the deuteron production in the gas. This is due to ionization by electron bombardment of free gas atoms.

I vote someone with such ideas actually test them out in a fusor. I am sure most ideas will work. How much improvement, if any, will be a matter of test by doing.
