Mildly interesting, but it doesn't appear relevant to a well of magnetically confined electrons as in a Polywell. Please note me how does plasma confined in other devices? Not magnetically? I am only putting the question: does in polywell electron beam injected into plasma? Or no? And I suffered wi...

Until we have those data all of our ideas can generate some nice discussions, but they will remain plain speculations. One more time about injecting of electrons into background plasma: That is just a simulation code. We all know that (with the proper conditions) you can get any result you want wit...

Ok, thanks. I am heating my soup pan and in result that is cooling. Am I correct?

KitemanSA wrote:Whatever collisions occur near the center of the volume, the resulting fuel ion must then climb up the potential well, converting kinetic energy into potential energy and becoming quite cold. Simple, no?

And I suffered with the question: why soup has cooled in my pan?

The idea is to increase the density inside the wiffleball, while keeping it low on the outside. The idea is to increase the density is attractive in any case. Because that allows to increase the power tapping from volume unit (as square). So, much smaller size of reactor. Not bad in any case. But a...

The theory is stating that thermalization will be avoided through: 1) The formation of the wiffleball plasma that will allow for 1,000 fold increase in density. 2)Thanks to the escape from the cusps of the thermalizing electrons that should be captured, reconverted to monoenergetic and re-injected ...

In case of Polywell I do not see any mechanism to avoid thermalization. D Tibbets gave you a reply in page2 of this thread. http://www.talk-polywell.org/bb/viewtopic.php?p=60058 Of course it still needs to be proven experimentally. Thank you. May be I missed something. Though after some reading now...

Will every collision be a fusion event? You should know the answer to that question for yourself, from the effort I put in trying to teach you and get you to read and think about it. Thanks for your efforts. And I am always open for learning. But unfortunately you are late this time. :) In case of ...

Can you explain me at the expense of what ions would be cold?
Do they not collide each other in the core of reactor?
Will every collision be a fusion event?

I already understood how this device is supposed to work. Also I assume how it will work in reality.

Beta=1 represents a peak in confinement efficiency... It's wrong. I also doubt in projected density 10^22 m^-3 that as I see is calculated from condition beta=1 (equality of gas and magnetic pressure). That will be impossible technically. And if lower density then consequently lower fusion intensit...

If by definition Beta cannot exceed one, then it might be more accurate to describe the Polywell of reaching 0.9999... Beta. If it manages to reach 1.000000.... the cusps open up and any additional electron current is wasted. This description does ease my ignorant concern about balancing at a Beta ...

For TOKAMAKs there was proved theoretically that in case if beta exceeds 0.4 then various types of instabilities will occur. See the point on good curvature above. It's not really an issue for mirror machines. In mirrors, the issue is cusp losses. The WB is meant to solve that problem. I do not und...

Indeed, AFAIK, in the Polywell, the pressure comes almost TOTALLY from electrons, fusion products adding a bit perhaps but fuel effectively not at all. I think that this is not a totally correct description. If you consider magnetic mirror as solid. Because in fact significant part of particles (in...
