直线电机Mistral轴向磁场中的等离子体旋转[A. Eur.Eur. J. D 56，209（2010）]通过假设从源注入的电子从中心柱径向离开并受到洛伦兹力而得到很好的描述。电子和离子通过双极性一起旋转。动量方程的解正确地预见了激光诱导荧光测量的离子径向速度的径向依赖性。这些方程的分辨率也与所测量的旋转频率对所施加的磁场和背景压力的依赖性很好地一致。
The plasma rotation in the axial magnetic field of the linear machine Mistral [A. Escarguel, Eur. Phys. J. D 56, 209 (2010)] is well described by the assumption that the electrons injected from the source exit radially from the central column and are subject to the Lorentz force. Electrons and ions rotate together by ambipolarity. The solution of the momentum equations foresees correctly the observed radial dependence of the ionic radial velocity measured by laser induced fluorescence. The resolution of these equations is also in good agreement with the measured dependence of the rotation frequency on the applied magnetic field and on the background pressure.
