>Assuming that at the "crunch" the fusor plasmoid deuterium ions have 20 KEV of kinetic energy, then I calculate their velocity is 1.38 X 10E6 m/s or about 0.5% of the speed of light. Perhaps the average expansion and contraction velocity is this. Then the plasmoid would have time to contract or expand only 0.015 cm in a cycle (distance = (ion velocity/velocity of light) X distance light travels in cycle = X 0.5% X X 12 cm). This seems much too small.

Why? Isn't all that matters the impact velocity?

>More realistic plasmoid oscillation diameters might be about 1 cm at the crunch and 7 cm at maximum expansion. This would need a RF frequency about 400 times lower or 6 meghz to drive it. This wavelength (equivalent to 50 m) makes resonant chambers too big to be useful, but a resonant chamber is not necessarily required.

What leads you to those numbers?

Always useful to think about new ideas for fusion in velocity space (kudos to Richard Hull for passing on that one liner!).
