As I remember developers talk not about heat losses due to interaction of environment: radiation or heat transfer but about a certain process by which angular momentums transfer into radial.
Please, if those "calculations or experimental evidence" are in Valencia paper (or somewhere else) quote them. As may be I missed something.
ok, i think i understand you. you mean like a micro collisional model, translating x to y to z. there are various 'packing' scenarios i can think of mediated by Coulomb force. there is also Lorentze force. (also indirect (out of system) control functions).
true, neither impose any 'directionality' in the sense of your enquiry i think.
the phrase 'transformation of angular momentum into radial momentum' does seem familiar however. i just cant remember exactly what has been claimed.
i have a vague memory of it relating to a net measurement effect (net energy balance equation), rather than a primitive physical mechanism.
as i recall there are a couple of good a japanese papers - one experimental ('multi-well' confirmation) , and the other theoretical (collisional/Folker Plank treatment). cant recall the links. sorry. they are on the board somewhere.

And I think very primitively: in case of scattering the declined particle can move strongly radially only in case if some forces will return it back.
yes. the well in the centre.

In any other cases it is impossible.
i think you are right. but it is possible. and that is the reason.

And all speculations about "reasonable time" during which plasma in Polywell can be kept cold are wrong. As quantity of scattering events strongly exceed fusion events' quantity.
that is your opinion. it is not an 'unreasonable' one. however, you must concede that to suggest that Bussard, Nebel, and the many other scientists in the field have totally overlooked this factor is to suggest they have absolutely no knowledge in the art, whatsoever. that would be absurd.
Bussard's calculations show there is such a 'window' of 'reasonable time' allowing acceptable fusion + acceptable thermalisation, steady state. the rest as they say as up to the scaling laws, and to go test the theory.
Since that time, more detailed computer modeling has been performed, in order to show it 'should work'. so far as i'm aware no commensurate computational effort has been put into showing ways it cant work. hence they build it.
personally i have my doubts too, on (out of envelope) thermalisation. (i would prefer to explore pulsed regimes, but there are many arguments against that also).
