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 thin...

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...

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

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...

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...

The grid is grounded.

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...

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.

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 ...

I think the issue with the line cusps is there is more statistical opportunity for gyro-radius 'matching' allowing particles to walk into and through the cusp. ???

New article from EMC2 in Journal of Fusion Energy.
Hopefully, this article provides some clarity for many on the actual progress and understanding these last years.
A slow road, however one which is still travelled...

I have been pondering the efficacy of going down from a six-sided to a four sided. Or, maybe a three sided. The primary loss mechanism is the point cusps, thus a reduction in their count seems logical. If you have a six sided machine, that is eight point corner cusps, and six ring center point cusps...

Flight 9 executed, arguably once again proving the axiom "Space is Hard". I would call it a 2 steps forward, 1 step back event. Booster 14 successful 2nd use for boost (B14-2), then died a heroic death testing the limits of re-entry to landing profiles. It made it all the way employing a high angle ...

In case you missed it... EMC2 has posted responses to some enduring "myths" about Polywell viability.
