提出了一个驱动托卡马克芯部等离子体极向旋转的新途径：用电子回旋波产生芯部等离子体极向旋转．物理机制如下：在高功率的电子回旋波加热的托卡马克等离子体中，共振局域化现象将产生极向电场从而形成极向外高内低的离子密度分布；这个极向离子的积累可以克服来自磁泵的阻尼而使等离子体极向旋转退稳定．从流体力学方程和漂移动力学方程中，得到了等离子体旋转退稳的判别式．结果表明现有的电子回旋波加热功率水平可以驱动芯部等离子体的极向旋转．
A new approach to driving the polar plasma of Tokamak core plasma is proposed. Electron cyclotron wave is used to generate the polar rotation of the core plasma. The physical mechanism is as follows: In a high power electron cyclotron heated tokamak plasma, the resonance localization phenomenon will produce a poloidal electric field to form an extremely high and low inward ion density distribution; the accumulation of this polar ion may Overcoming the damping from the magnetic pump to stabilize the plasma in polar rotation. From the hydrodynamics equation and drift dynamics equation, the discriminant of the plasma rotation stabilization is obtained. The results show that the existing electron cyclotron heating power level can drive the polar rotation of the core plasma.
