Electron Bernstein waves in spherical tokamak plasmas with "magnetic wells"

摘要:

除了传统的单调递增磁场区域外,球形托卡马克(ST)中还存在“磁阱”区域。磁场剖面反演显著地改变了波的传播和衰减的整体图像。由于磁阱可能会变得相当普遍的ST性能的进一步改善,这种配置的分析是感兴趣的EBW等离子体加热的CD前景的评估。本文研究了平板模型中电子束波传播和二次回旋谐波衰减的基本特征。

英文摘要:

In addition to traditional regimes with monotonously increasing magnetic field, regimes with "magnetic wells" also occur in spherical tokamaks (STs). The magnetic field profile inversion modifies significantly the whole picture of the wave propagation and damping. Since the magnetic wells may become quite common with further improvement of ST performance, analysis of such configurations is of interest for assessment of EBW plasma heating an CD perspectives. In this paper the basic features of the EBWs propagation and damping for the second cyclotron harmonic in a slab model are considered.
