Non-linear coupling of kink modes in tokamaks

R.Y. Dagazian1976年被引用 3Nuclear FusionIF 3出版社

The m = 2, n = 1 kink mode is shown to be capable of destabilizing the m = 1, n = 1 internal kink. A nonlinear Lagrangian theory is developed for the coupling of modes of different pitch and is applied to the interaction of these modes. The coupling to the m = 2 mode provides sufficient additional destabilization to the internal mode to permit it to account even quantitatively (where it had failed when considered by itself) for many of the features of the disruptive instability.

m = 2, n = 1 キンクモードは、m = 1, n = 1 内部キンクを不安定化させ得ることが示される。異なるピッチを持つモードの結合に対する非線形ラグランジアン理論が展開され、これらのモードの相互作用に適用される。m = 2 モードへの結合は、内部モードに十分な追加の不安定化をもたらし、それにより内部モードは(単独で考えた場合にはそれが失敗していたが)ディスラプティブ不安定性の多くの特徴を定量的にさえ説明することが可能となる。
