I have ranted at length about such things in the past if you check the archive. The high grid loss is probably in large part the result of nonfusing collisions thermalizing (randomizing) the ballistic paths of the ions, causing them to fall into the grid.
All the ions try to enter and exit the sphere in the same paths. They accelerate in a diverging field, and experience electrodynamic geometric anisotropic fields too.
By embracing the natural instabilities that would simply radiate energy away as RF, it may be possible to drasticaly reduce grid losses and create focusing and accelerating structures.

In the old (before PC) days they use to put grids in a saltwater bath to plot the E-fields.
But the realy interesting high-energy stuff is electrodynamic and self-interacting with the plasma. I'll bet iterative simulations/experimentation is the only way to go, and even then your still dealing with a chaotic media. Feel luck? Bwahhhahhahahaha 8^)
But that is why a hacker might excel where an army of dumbed-down dweebs fail.
>I am thinking of a 'pasta' pot size reactor core.
It recently occured to me that we may have an advantage that the Tokamak folks don't - size. Some phenomena only happen at small scales, such as vortices. It may be that microscopic fusion reactions can be stabilized but large scale structures are self limiting.
In such a case a viable reactor would be an array of small reactions, like the multiple elements of a furnace or power mosfet rather than one big reactor.

Know an efficient way to brew some?
