Including instabilities in solar, astrophysical, and space plasmas
[edit]In the current version of this article, nearly all of the focus is on plasma stability in laboratory plasmas. From that perspective, the article is in very good shape. However, one thing that would greatly help the article would be to include plasma instabilities in different environments. For example, plasma instabilities play a very important role during solar eruptions and in accretion disks during star formation. Additionally, the mode number decomposition makes sense in periodic plasmas such as those in a torus, but they are not as widely used or applicable in astrophysics (with some exceptions such as accretion disks and jets). It would be helpful to broaden the focus and have separate sections to discuss instabilities that occur in different environments. Spacehippy (talk) 22:43, 16 January 2014 (UTC)
Internal contradiction
[edit]> MHD theory is the simplest representation of a plasma, so MHD stability is a necessity for stable devices to be used for nuclear fusion, specifically magnetic fusion energy. [...] There are also rare cases of systems, e.g. the Field-Reversed Configuration, predicted by MHD to be unstable, but which are observed to be stable, probably due to kinetic effects.
That figures, because the "simplest representation of a plasma" seems like a loosy-goosy way of talking about it. MHD was an approximation if i remember correctly?88.159.74.173 (talk) 12:51, 1 November 2015 (UTC)
No mention of high-confinement mode (H-mode)
[edit]high-confinement mode (H-mode) Should be in this article or tokamak ? Not covered anywhere in WP ! - Rod57 (talk) 14:32, 6 December 2015 (UTC)
