Heating and flow drive by low frequency waves in high beta plasmas

在磁约束等离子体合并过程中，通过磁重联在高β区激发低频波。这些波部分促成了从磁能到离子热能的转换。当重联中存在明显的垂直于重联磁场的引导磁场时，单调的大幅波被激发为动态阿尔文波。然而，这些波并不是提供观察到的离子加热的主要因素。另一方面，当没有引导场时，极低频波被全局激发。这些剪切阿尔芬波直接驱动离子流动，并最终提供从磁性到离子热能的转换。结论是，这些极低频波适用于高β等离子体的加热方法。

Low frequency waves are excited in the high beta region of magnetically confined plasmas by magnetic reconnection during plasma merging process. These waves partly contribute to the conversion from magnetic energy to ion thermal energy. When the reconnection includes significant guide magnetic field perpendicular to the reconnection magnetic field, monotonic large-amplitude waves are excited as kinetic Alven waves. However, these waves are not dominant factors providing the observed ion heating. On the other hand, when there is no guide field, very low fewquency waves are globally excited. These shear Alfven waves directly drive ion flows and eventually provide conversion from magnetic to ion thermal energy. It is concluded that these very low frequency waves work for the heating method for high beta plasmas.
