镜像离子回旋模式与电磁离子回旋模式的竞争

On the competition between the mirror and electromagnetic ion cyclotron modes

R. A. Treumann, O. D. Constantinescu

摘要:

本文给出了各向异性高$β$等离子体中镜像和电磁离子回旋模式的唯一存在性的简单论证。结果表明,除了一个大的域的共存的两种模式,两个域存在于参数空间$(A,β_\perp)$中,只有镜像模式或电磁离子回旋模式可以被激发。在重叠区域,增长率较大的模式应该获胜。然而,非线性效应可能会改变这样的结论。

英文摘要:

We give a simple argument for the exclusive existence of mirror and electromaghetic ion cyclotron modes in anisotropic high-$β$ plasmas. It is shown that, in addition to a large domain of coexistence of both modes, two domains exist in parameter space $(A,β_\perp)$ where solely either mirror modes or electromagnetic ion cyclotron modes can be excited. In the overlap region the modes with the larger growth rate should win. However nonlinear effects may modify such a conclusion.
