Could this be the Lockheed-Martin design?

Thinking about the Field Reversed Configuration magnet layout, it occurs to me it has 2 magnetic wells, each with a single cusp leading out. (And a line cusp leading to the other well.)
Magnetic wells highlighted in purple.
Idea: Positive charge on the outer magnetic toroids. An electron beam feeding an excess negative charge in pollywell style. Ion confinement and electron recirculation polywell style.

Looks like it would make a nice thruster.

Or coupled to a magnetohydrodynamic generator

Hmmm...

Skunkworks is working on a high-beta reactor

Magnetic containment, radio frequency induced heating. Appears to use a magrid like polywell. The radio frequency heating seems to be the added touch that allows for a more compact reactor than Bussard's scaling law would allow.

That's pretty much the conclusion I came to as well, based on the limited evidence at hand.

RF heating, neutral gas injection, let differential leakiness of the wiffleball produce a net charge without electron beams? Might work. As a bonus, could RF input plug cusps?
