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.
Of course, that's the fun of it
. Actually, I think you misunderstand me a bit -- I'm not thinking of quickly oscillating back and forth pulsing, but a rapid series of discrete pulse pairs. First, the ionization pulse, a few microseconds long, at a voltage only slightly above that of the keep-alive voltage and of high current, in order to produce the max number of ions. That is almost immediately followed by the fusion pulse, which is of much higher voltage, applied to the inner grid, and of high current. It should probably last as long as the available capacitors and power supply can make it. After that, there is a dead time of several milliseconds while the caps recharge for the next pulse.
