Are you sure your calculations are stable? I think I saw similar "weird" behavior with ephi if I reduced calculation resolution too much.

Without the electrons? As in without the potential well - just a plain system with no charges? You can see them here, well not really 3D plots but 2D color-maps (color/elevation - same thing - potential): http://www.mare.ee/indrek/ephi/pef8/ Note: the charge within the polywell in that page is an id...

You assume correctly about the x and y. The z axis represents the potential. 0 (ground) up to +10KV (the coils). Flawed in a sense that the effective well depth is almost nonexistent - ions can escape through the faces at already very low energies - no matter that the voltage is quite low in the mid...

The short answer would be: none of the above. Probably. As I'm not really sure what ballistic ions or boltzmann electrons are ;). I am a product of google and wikipedia and I am an amateur so probably I did something unconventional, probably something very wrong. For my dayjob I program web pages an...

The coils are directly charged at +10KV - like the grid in a fusor - using transformers and wires and stuff. The force the ion experiences is not dependent on the particular voltage number (or color) but rather at the rate of change in the potential at the point where the ion is. The force the ion e...

No Steve. The red region near the coils is at +10KV. The black is ground (0V). The red-yellow-green-black transitions form the potential gradients. The ions want to move from the higher potential to the lower potential. The idea for fusion is that the ions are added at the edge of the middle lower p...

My point there was not as much as that the well won't form at all but rather the _effective_ well depth for ions will be limited due to the coils having big holes in them (the other half of this mail is actually about an entirely different idea - you have to read the thread). Going further have a lo...

Very good. I once tried to pick the same thing up on the iec fusion list but nobody took the bite:

Using Vizimag (2D only) I made a polywell equivalent. The field vectors are thus:- As far as I understand, the field vectors indicate the direction an electron might experience force upon itself if it were at a particular point; and the intensity indicates the magnitude or size of that force. Thus,...

Recirculation is essential. But I don't think it says anywhere recirculation means "making circles around coils". I think there's some confusion here. Electrons do move through between the coils, so open system is essential (with high potential coils), that's true. The simulators show that as well. ...

Actually. As this is the only very obscure way I have seen electrons making full circles around the coils (following field lines "back" into the system), I don't believe recirculating electrons would practically ever make it out one cusp and in another. The field lines don't allow that (near the cen...

What I meant by electron going around the coil and also round the coil is this: http://www.mare.ee/indrek/ephi/double/round.png Well I'm not sure whether things like this will dominate the process cause I have to play with parameters a bit to get something like this (have to give enough energy to pe...

To get good full round circulation along field lines from and back into the machine for electrons that have picked enough energy to escape the coil potential (our problem fast electrons) the machine would have to be huge But can't you decrease how far out they get by increasing the positive charge ...
