Electrothermal instability

Hi Tokamac, Where did you get the article Electrothermal instability from? Thanks. --Bob K31416 (talk) 02:29, 15 September 2008 (UTC)[reply]

Hi -Bob K31416, so many years later, sorry… I never went to this page. At that time I used to know an old plasma physicist (specialist in the field of nonthermal plasmas and magnetohydrodynamics) who trained me a bit about this subject with little course, original books and two thesis to read (his own thesis and the thesis from his graduate student). Alas the electrothermal instability is a very hard science not teached anymore since the 60s-70s. Tokamac (talk) 19:10, 2 March 2013 (UTC)[reply]

Polywell: Electron cloud is non-thermal?

Through the many years we have all watched the polywell, two major questions have always existed:

Are the electrons in the center, non-thermal?
Does the electron cloud go diamagnetic?

If both were true, it would be huge. A non-thermal cloud means the Lawson criteria may not apply. (Gasp!) It also means Rider's criticisms may be less applicable. (A big deal). EMC2 new publication partially answers the second question: electron diamagnetism. They put a loop of wire into the plasma and measured the electron cloud exhibiting a real "extra" magnetic flux. This combined with an X-ray signal - detected from the cloud - was used to suggest the electrons have two modes: a low and high beta mode. In low beta, the confinement sucks. In high-beta, the electron cloud is diamagnetic, confinement Hell-a-rocks! The data suggests a clear switching between each. But, I am not convinced we have a data showing the cloud is non-thermal. (Prove me wrong?)

It is REALLY hard to accept this cloud does not go to a bell curve, considering how many electron-ion and electron-electron interactions are taking place and that bell curves are some of the most accepted concepts in all of science, engineering or mathematics. So Saying: "The Lawson criteria does not apply because the plasma is not a bell curve" in this wikipedia article does gives me a sickly feeling. Can you explain the edit?

I am aware there is non-thermal plasma in the world. I am just not convinced that we have evidence showing it in Polywells. We know that is how polywells are supposed to work, but can we really yet prove they do work that way?

You're right. It's not clearly proven yet, so I modified the text I added. It was conjectured by Bussard, and EMC2 tries, through MaGrid, to:

decelerate the hot electrons escaping the center with their recirculation through the field lines
remove the upscattered electrons from the system, before they thermalize (so that electron lifetime < electron thermalization time); and replace them with new electrons of fewer energy.

Like you, I hope to see new evidence soon that this is the case.

Cut-and-paste move

Hi, and thank you for your contributions to Wikipedia. It appears that you tried to give Direct conversion a different title by copying its content and pasting either the same content, or an edited version of it, into Direct energy conversion. This is known as a "cut-and-paste move", and it is undesirable because it splits the page history, which is legally required for attribution. Instead, the software used by Wikipedia has a feature that allows pages to be moved to a new title together with their edit history.

In most cases, once your account is four days old and has ten edits, you should be able to move an article yourself using the "Move" tab at the top of the page (the tab may be hidden in a dropdown menu for you). This both preserves the page history intact and automatically creates a redirect from the old title to the new. If you cannot perform a particular page move yourself this way (e.g. because a page already exists at the target title), please follow the instructions at requested moves to have it moved by someone else. Also, if there are any other pages that you moved by copying and pasting, even if it was a long time ago, please list them at Wikipedia:Cut-and-paste-move repair holding pen. Thank you. Kolbasz (talk) 21:35, 24 June 2014 (UTC)[reply]

Thanks, and sorry. I wasn't aware of this functionality. I asked to repair this with {{histmerge}}. Tokamac (talk) 22:32, 24 June 2014 (UTC)[reply]

A barnstar for you!

	Fusion Barnstar
	Very nice edits on Polywell and Direct Conversion. I very much liked the conversion page, there was plenty of new information. This "cut and paste" move taints this star a bit, but ok. WikiHelper2134 (talk) 03:52, 26 June 2014 (UTC)[reply]

Hello - I am working through the text on direct conversion... it looks like your the expert. I purpose we work together to get the most accurate information out. Let me know if your interested.

Well… LOL? If I can give you a simple advice, don't pay too much attention to autistic wikipedians, they act on a web site like if their whole life depended on it and nothing exists outside. The guy really just should get a life, especially during Christmas time. As for me I won't follow on this hysterical logorrhea. — Tokamac (talk) 11:43, 24 December 2016 (UTC)[reply]

List of unsolved problems in physics

Hi, I made a "mistake" of editing wikipedia again. :/ If you agree with my point of view (which, based on the evidence, I strongly believe to be correct), would you care to support me in the talk page and perhaps let know other interested people about this, so that they also could support these edits, if they wish? Only the discussion of today matters, because only today it became substantive (though opponents so far have not provided with any evidence (no links to sources) to their point of view). Many thanks in advance.Musashi miyamoto (talk) 17:10, 21 January 2018 (UTC)[reply]
