A kinetic theory of the magnetic islands merging instability

L M Zeleny, A L Taktakishvili1988年Plasma Physics and Controlled FusionIF 2.2出版社

Collisionless kinetic theory of the merging instability of magnetic islands is presented. Merging instability results in a very fast coalescence of attracting magnetic islands and may play an important role in magnetic energy release in solar flares and laboratory plasma devices. The general picture of merging instability regimes dependent on the value of magnetic shear and magnetic island width w is sketched. The new kinetic regime of collisionless coalescence with gamma approximately w1/2 which operates in a very wide parameter range is discussed in detail.

無衝突運動論に基づく磁気島の合体不安定性の理論を提示する。合体不安定性は、互いに引き合う磁気島の非常に高速な合体をもたらし、太陽フレアや実験室プラズマ装置における磁気エネルギー解放において重要な役割を果たす可能性がある。磁気シアおよび磁気島幅wの値に依存する合体不安定性の各領域に関する一般的な描像を概説する。非常に広いパラメータ領域で作用する、ガンマがおおよそwの1/2乗に比例する新たな無衝突合体の運動論的領域について、詳細に議論する。
