Isotropy of ion heating during a sawtooth crash in a reversed-fieldpinch

D J Den Hartog, D Craig2000年Plasma Physics and Controlled FusionIF 2.2出版社

In the Madison Symmetric Torus reversed-field pinch, ions are impulsivelyheated during a sawtooth crash; the ion temperature more than doubles. Heatingappears to be nearly isotropic; the impurity ion temperature measuredperpendicular to the magnetic field (T⊥) is approximately equal to impurityion temperature parallel to the magnetic field (T∥) during a sawtoothcrash. Ion heating occurs simultaneously throughout the entire plasma volume,with no non-Maxwellian distortion of the ion velocity distribution function.

マディソン対称トーラス反転磁場ピンチにおいて、イオンは鋸歯状波クラッシュ中に衝動的に加熱され、イオン温度は2倍以上に上昇する。加熱はほぼ等方的であり、磁場に垂直な方向に測定された不純物イオン温度(T⊥)は、鋸歯状波クラッシュ中に磁場に平行な方向の不純物イオン温度(T∥)とほぼ等しい。イオン加熱はプラズマ全体で同時に発生し、イオン速度分布関数の非マクスウェル的な歪みは見られない。
