摘要

本文综述了托卡马克高温等离子体中Alfvén波和ICRF波全局结构的理论和数值研究。发展了非均匀色散介质中波动方程的动力学理论。将波动方程作为边值问题求解,以提供对天线激励、射频波传播和吸收的一致描述。获得了波形、功率沉积轮廓、等离子体物质的功率分配和天线阻抗。文中还讨论了求解的数值过程、精度以及计算性能。

Global waves in hot plasmas

This article reviews theoretical and numerical study on the global structure of Alfvén and ICRF waves in the high temperature plasmas confined in tokamaks. The kinetic theory of the wave equation in an inhomogeneous and dispersive medium is developed. The wave equation is solved as a boundary value problem to provide a consistent description of the excitation by an antenna, propagation and absorption of the rf waves. The wave forms, power deposition profile, power partition by plasma species, and the antenna impedance are obtained. The numerical procedure and accuracy of the solution as well as the computational performance are also discussed.
