Now I have done magnetic field simulations of the arrangement I have shown in my previous post. Taking Art Carlson's definition of cusps being places from which field lines go to regions of zero magnetic field strength, here are the lines through cusps: http://www.broadbit.net/download/polywell/Sphe...

Here is a cross-over between my original proposal of 3 spherical rings and hanelyp's 'spherical WB-6'. It is composed out of 'equatorial arc segments'. There are 6 square-like faces and 8 hexagon-like faces. The last image shows enclosure of whole arrangement in tornado-trap. Red lines: input curren...

spaccemonkey says: The charge on the magnetic grid is not relevant to the behavior of a charged particle inside it's volume I was talking about turning back electrons moving outwards, when they are OUTSIDE the Polywell grid. It seems my English was not clear enough - don't assume right away that I ...

I made an update to the grid geometry analysis: http://www.broadbit.net/download/Spherical-Polywell-geometry_v2.pdf A small change in the 'spherical octahedron' grid prevents junctions at zero magnetic field, without making any significant difference to the inner field lines. (just to settle the wor...

Cusp loss and recirculation is the same mechanism in all setups. In fact the distance for the recirculating electron to travel is shorter in my proposal than with WB-6/7. (with similar gird dimension) That is significant because recirculation ratio depends on mean free path. Whether electrons hit th...

as MSimon points out, it has coils running through field null points. True, but the space surrounding these points has non-zero field; as shown in the simulation diagram approaching electrons are steered away. Or do you think electrons could still hit these points for some reason? That could be rec...

Spherical and hierarchic grids
I am puzzled by the persistence of using 'almost polyhedron' shaped grids, instead of more spherical geometries. Here is a link to a grid arrangement I thought up, made of 3 rings: http://www.broadbit.net/download/Spherical-Polywell-geometry.pdf The descriptions lists some advantages of it, compared...
