Abstract

In the limit of sufficiently fast rotation, rotating mirror traps are known to be stable against the loss-cone modes associated with conventional (non-rotating) mirrors. This paper calculates how quickly a mirror configuration must rotate in order for several of these modes to be stabilized (in particular, the high-frequency convective loss cone, drift cyclotron loss cone and Dory–Guest–Harris modes). Commonalities in the stabilization conditions for these modes then motivate a modified formulation of the Gardner free energy and diffusively accessible free energy to be used for systems in which the important modes have wavevectors that are orthogonal or nearly orthogonal to the magnetic field, as well as a modification to include the effects of a loss region in phase space.
旋转镜中的损耗锥稳定:阈值和热力学
众所周知,在足够快的旋转极限内,旋转反射镜陷波器可以稳定地对抗与传统(非旋转)反射镜相关的损耗锥模式。本文计算了镜面配置必须以多快的速度旋转才能稳定其中几种模式(特别是高频对流损耗锥、漂移回旋损耗锥和多利-盖斯特-哈里斯模式)。这些模式稳定条件的共性促使我们对加德纳自由能和扩散自由能的公式进行修改,以用于重要模式的波矢量与磁场正交或接近正交的系统,以及包括相空间损耗区效应的修改。

期刊介绍: JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
