I see I'm a little late to the discussion, but this is very similar to the patented Fusion device I've been proposing for several years here. http://www.DDproFusion.com
The main idea behind my reactor is to contain NIF like explosions in magnetic fields. I've been trying to get a test reactor built for a long time, and my plans have been hampered by a theft earlier this year.
A huge difference between the current NIF device and my proposed device is the speed of implosions and the strength of the field. While the NIF device must be re-built before every implosion, my device creates an environment where the implosions form as part of a harmonic oscillation. The ions are allowed to travel their entire individual cyclotron trajectories before they return to the implosion site... my target frequency was 2.4GHz, which is a useful frequency for direct conversion and COTS components.
