Isn't that a tokamak type design? Dr. B was rather familiar with those (he worked on them before he came up with the Polywell concept). If he did not do it that way he must have had a reason.chrismb wrote:I still don't understand (and have never had an answer when posting the suggestion) why a toroidal solenoid would not do the whole job better. If the whole way Polywell works is some 'multi-species' collective behaviour of ions and electrons, rather than the flat density of both that Art and I expect, then;
why not confine electrons around the central major radius of a toroidal solenoid, then inject the ions into it along poloidal radii? In poloidal cross-section, this would look exactly like any of the diagrams of Polywell, just without the cusps!! If the annealing process works as advertised, then this will deal with ions scattered 'toroidally', just as Polywell should do for those ions scattered at some radius away from the centre.
BTW where in the toroid do you put the accelerator grids? And how do you shield them? And how do you create the well?
