Ok decided to use COMSOL plasma physics to model the FEM model of the oscillating field coils. Also will look into NairnFEAMPMViz a MDM PIC FEM modeler, though it seems literature on how to use it isn't explicit. It may take a while to authorize a version of the COMSOL but will try my best as the gr...

Actually also if my theory of the oscillating field winding is correct about being a gridless accelerator, I can explain the reason for the third coil as well in the center of the two opposing Helmholtz coils. Its just kind of falls out so I'm getting a bit pumped if only the FEM software can prove ...

Hi Dan, From the Wiki of biconic Cusps I've posted the picture a quote of text below: Unfortunately for some reason the image isn't showing up inline. So please all go set your browser address to: http://en.wikipedia.org/wiki/File:Biconic_Cusp.jpg http://en.wikipedia.org/wiki/File:Biconic_Cusp.jpg "...

On that note of Carnot efficiency conversion it would also be much easier to thermally absorb and insulate the fusor furnace if compact versus several apartment buildings large.

"It helps a lot if, unlike the tokomak, the magnetic field can contain plasma at near beta=1 and doesn't suffer from turbulence related to the field weakening when the plasma pushes it out of nominal position. You still need a magnetic field several gyroradius thick between the plasma and the first ...

Hi Dan, Well I went to bed last night recognizing the folly of arguing against the loss of ExB and containment of neutral plasma. I also realized that my idea of of charged particle containment was corkscrewy (literally) in explaining the interactions of charged particles to the external magnetic fi...

You are correct about ExB losses. I did a bit of study and realized how much was lacking on my part. Appreciate your patience all and think I'll return to RF engineering instead of plasma studies. :D. It has been fun and I saved myself a few hours using Ansoft plasma solutions. I'm removing a lot of...
