This 3D model is taken from information in the preprint paper: "High Energy Electron Confinement in a Magnetic Cusp Configuration." by Dr. Jaeyoung Park, et. Al. on June 1, 2014. This is a polywell. A polywell uses an electric field to heat ions to fusion conditions, it could be a path to fusion power. This model is incomplete (there were other holes in the chamber, not shown), but does show the ring structure, supporting apparatus, chamber and diagnostics. Also included are the plasma and electron injectors. The film shows the machine, labelled parts and some dimensions.

brought to you by Sketchup! :)

btw, are those dimensions centimeters?

The coaxial cable does appear to be a pair of "stove support rings" as opposed to a simple single loop. The only difference I would suggest is to have its legs extending past the inside margins of the magnet can as opposed to butting up against it. This device, while necessary for measuring B field flux, had to be a tremendous sink for plasma, adversely effecting confinement and probably heat loss as well.. I am guessing scaling projections has more to do with WB8 work, rather than this purpose built machine.

The two plasma guns look reasonable, but I think there was only one electron gun placed on the top side.
It was biased at ~ neg. 7000 volts and could provide ~ 2 Amps of electron current according to the paper.

Otherwise a nice graphic. Additions of visible light cameras, spectrographs and especially the filtered X-ray detectors at the face and corner windows would illustrate the instrumentation used to obtain the definitive data and emphasize the importance of this experimental setup for achieving the goals in a difficult pulsed operation machine..

OK as far as it goes, but the picture of the lab in Alan Boyle's latest story shows a big stainless steel drum with a yellow end stuck off the side. Presumably there is another on the other end. What the heck ARE they? The plasma guns?

Green magrids? Sheesh, can't they be rendered in silver? ;)

The "big stainless steel drum with a yellow end" is on WB8, not the machine in the video.

Wishful thinking on my part, I guess. "Navy Machine" is kind of vague. Most of the WB series qualify. Not sure about WB-1, which may have been "the American Science and Surplus Machine." And I'm not sure of the funding for the construction of WB-2, but I know I ran it under a Navy contract.

Dr. Park is standing just to the right of Mini-B.

Tom, if you look behind WB-8 you can see the panels. No space for another big "yellow" monster mystery device. ;)
