A simple model of large amplitude helical instabilities in the Z pinch

M. Coppins1993年被引用 2Nuclear FusionIF 3出版社

A simple model of the development to large amplitude of the m=1 (helical) mode in the Z pinch is described. It is shown that the large inductance changes associated with this instability, and the interaction between the pinch and the external circuit play crucial roles in the phenomenon. A criterion for the 'most unstable' wavelength is given. The absence of long wavelength modes, and the origin of the rapid expansion, observed in this type of instability, are explained

Zピンチにおけるm=1(ヘリカル)モードの大振幅への発展の簡単なモデルについて述べる。この不安定性に伴う大きなインダクタンス変化と、ピンチと外部回路の間の相互作用が、この現象において決定的な役割を果たすことが示される。「最も不安定な」波長に対する判定基準が与えられる。この種の不安定性で観測される長波長モードの欠如と急速な膨張の起源が説明される。
