Plasma confinement in the m=1, n=1 kink distorted tokamak central core

S.V. Putvinskij1993年被引用 7Nuclear FusionIF 3出版社

It is shown that the kink distortion of the magnetic axis and, as a consequence, the variation of the magnetic field along magnetic surfaces in the toroidal direction lead to a new type of 'superbanana' particle orbits and can drastically change the classical particle and heat transport in the central core. The phenomena discussed have a time-scale of approximately=10-3 s and seem to be too slow to affect the sawtooth crash process (which is an order of magnitude faster). They can, however, influence the evolution of the plasma parameters between crashes, the formation of 'snakes' and other phenomena in the central plasma inside the q=1 magnetic surface

磁気軸のキンク変形と、その結果としてトロイダル方向における磁気面上の磁場の変化が、新しいタイプの「スーパーバナナ」粒子軌道を生じさせ、中心コアにおける粒子輸送および熱輸送を劇的に変化させ得ることが示される。議論される現象の時間スケールは約10⁻³秒であり、鋸歯状波のクラッシュ過程(その時間スケールは一桁速い)に影響を及ぼすには遅すぎるように思われる。しかしながら、それらは、q=1磁気面の内側の中心プラズマにおける、クラッシュ間のプラズマパラメータの時間発展、「スネーク」構造の形成、その他の現象に影響を与え得る。
