This will collect all the fuel ions in the region of the outer grid. Then, as this pulse drops off, you pulse the inner grid, accelerating this ion popualtion into the central region etc. This is superior to pulsing the inner grid in the ionization pulse b/c it results in the population of formed ions being at the edge of fusor. Thoughts?
A god idea, but a lot of effort and imperical research would be needed to determine the optimum times and delays involved. I would imagine a near microwave frequency with long colection times might be required. This would be the result of a study of the reversal and acceleration times of the particles.
Reversing ions and having them ideally return might have them wind up becoming neutrals in a relatively high pressure chamber (10u). Remember, the type pressures we are dealing with are not highly conducive to a lot of recirculation. (tradeoffs.)
It is worth a shot for the well heeled and adventurous amateur.
