Re: Polywell revisited

Kite, nobody says "funny cusps" any more. The coil edge to edge cusps have been shown to have essentially no losses. All the (e-) losses are via the cusps in the center of each coil (6 of them) and via the corner vertices cusps (8 of them), for a total of 14 cusps of concern. And, as I understand, t...

Re: POLY-TOK?

I have seen all the devices, and none were wound toroidally. They have always been coils (wire loops). And, yes I agree, the coil being circular or flat sided has minor influence on the field dispositions, especially when placed with other coils. When I say to Toroidally wound, that means the wires ...

Re: Polywell revisited

The line cusps found on the edges of the cube are not really leaky. The point cusps at the corners (8 of them) and the point cusps at the centers of each face (6 of them) comprise the 14 leakage points of concern. Charging the coils is unnecessary for DT, and may not be needed for P-B11 the way thi...

Re: POLY-TOK?

What we are getting at here is the coil configurations being Helmholtz or anti-Helmholtz. To be clear, the Polywell coils have been wound as solenoids, and not toroidal. Trap configurations dictate anti-Helmholtz with the opposing coils having opposite current flow and thus orient the B field poles ...

Re: POLY-TOK?

Yes, I mean the Line cusps found at the parallel field edges on the sides of the cube, vice the point cusps found at the corner faces where three or more fields interact, or the point cusp found in the center of the 'donut', where the toroid interacts with it's own field. I do not agree with your ar...

Re: EM Drive

The real question here is do they have enough support ($$$) to build a corrected vehicle and do another launch?

Re: Polywell revisited

Y'all really should read the latest published work. It speaks to much of which you debate. The shot based machines taught the team much, up to and including WB-X. The simulation work has validated and extended the physical data learning even further. The next logical step in the research is to compl...

Re: POLY-TOK?

From a field perspective, magnets are magnets. How the fields interact remain the same. You went where I was headed, the edge cusps can couple with that arrangement. And, as noted, the point cusps at the 'merge' will not. And, the center cusps on each coil will also still exist. For the coupled edge...

Re: POLY-TOK?

No matter how I arrange faces, given the magnets are polar, to have aligned/coupled seams, you need to alternate the fields (Clockwise/Counter-clockwise). This still results in both edges and points where the fields oppose and don't couple. The linked paper helps show what I am talking about. Grante...

Re: Polywell revisited

From what I have seen, the exiting (e-) are gone once they couple to the field lines. No recirculation from the outside. They either reflect back into the core, or go away.

Re: POLY-TOK?

Ok, however won't there be a cusp no matter given you are bringing opposing magnetic fields together at a 'joint', for lack of a better term. The shape of the magnet doesn't negate the fields opposing and creating a 'joint'. Maybe I am missing something here. Maybe I need to go back and look at what...

There is absolutely a learning which occurred in the sequencing of the startup. I have read the work. In essence, one must inflate the balloon before providing fuel: Magnets on, Large (high power) influx of electrons to rapidly inflate the plasma to Beta = 1 within the magnetic confinement (Balloon ...
