| 摘 要： | 研究了旋转磁岛与反平行于磁场运动的通行快离子共振所诱发的快离子输运.结果表明:对于每一个快离子能量存在两个最大共振点,共振投掷角区的宽度比其他点更宽,分析了共振产生的漂移岛面,发现漂移岛面在等离子体边界存在间隙,存在三种类型的漂移岛面,对应三种不同的快离子输运路径.

| Abstract: | The passing fast ion transport,which is induced by resonant interactions with a rotating island,is investigated in this article.There are two maximum resonant points for each fast ion energy,where the widths of resonant pitch angles are larger than those of other resonant points.The drift island surfaces produced by the resonances are analyzed.The pitch angle gap near the plasma boundary is found.There are three kinds of drift island surfaces,which correspond to three kind of transport paths,respectively. |
