快波少子加热的数值研究

Computational research on fast wave minority species heating

介绍了离子回旋波加热领域研究进展,具体分析了快波少子加热模式转换情况以及影响模式转换分量大小和位置的因素。通过控制波的频率及少子浓度,使得波能够顺利传播到托卡马克等离子体的离子混合共振与截止的区域附近,并转换为离子Bernstein波而被等离子体有效吸收,因而能够改善加热效果。

Advances of research on then domain of ion cyclotron wave heating are introduced, and mode conversion of fast wave minority heating, as well as the factor to influence the fraction and position of absorption is analyzed in detail. By means of controlling wave frequency and minority concentration, it is possible for the wave to be propagated near tokamak plasma central ion hybrid resonance region and effectively absorbed by the plasma by being converted to ion Bernstein wave, so the heating effect is improved.
