The physics model of electron cyclotron heating (ECH) and current drive (ECCD) is becoming well validated through systematic comparisons of theory and experiment. This work has shown that ECH and ECCD can be highly localized and robustly controlled in toroidal plasma confinement systems, leading to applications including stabilization of magnetohydrodynamic instabilities like neoclassical tearing modes, control and sustainment of desired profiles of current density and plasma pressure, and studies of localized transport in laboratory plasmas. The experimental work was supported by a broad base of theory based on first principles which is now well encapsulated in linear ray tracing codes describing wave propagation, absorption, and current drive and in fully relativistic quasilinear Fokker–Planck codes describing in detail the response of the electrons to the energy transferred from the wave. The subtle balance between wave-induced diffusion and Coulomb relaxation in velocity space provides an understandin...

电子回旋波加热和电流驱动

电子回旋加热 (ECH) 和电流驱动 (ECCD) 的物理模型正通过理论和实验的系统比较得到很好的验证。这项工作表明，ECH 和 ECCD 可以在环形等离子体约束系统中高度局部化和稳健控制，从而导致应用包括稳定磁流体动力学不稳定性，如新古典撕裂模式，控制和维持所需的电流密度和等离子体压力分布，以及研究实验室血浆中的局部传输。实验工作得到了基于基本原理的广泛理论基础的支持，这些理论现在很好地封装在描述波传播、吸收、和电流驱动以及完全相对论的拟线性福克-普朗克代码，详细描述了电子对从波转移的能量的响应。速度空间中波诱导扩散和库仑弛豫之间的微妙平衡提供了一种理解……
