旋转磁场电流驱动是一种既能增加磁通又能维持电流的方法。它已在低温、低场旋转轨道器中得到证实，现在将应用于一个新的平移、约束和维持（TCS）实验，该实验附在LSX/mod（大s场反向位形实验）设施上[霍夫曼等，聚变技术，23，185（1993）]。以前的RMF计算主要关注的是在一维圆柱体中产生的等离子体电流和粒子轨道，旋转场强度与限制轴向场的大小接近相等。这里，流体流和粒子轨道都是在适合于TCS和反应堆的更有趣的区域中计算的，其中限制场远远超过旋转场强度。新的洞察力是获得到两个通量建设的要求，二维平衡和离子旋转的限制，在这个高配置…
Rotating magnetic field (RMF) current drive is a very attractive method for both increasing the flux and sustaining the current in field reversed configurations (FRC). It has been demonstrated in low temperature, low field rotamaks, and will now be applied to a new translation, confinement, and sustainment (TCS) experiment attached to the LSX/mod (Large s field-reversed configuration Experiment) facility [Hoffman et al. Fusion Technol. 23, 185 (1993)]. Previous RMF calculations have been concerned primarily with the plasma currents and particle orbits produced in one-dimensional cylinders with the rotating field strength of near equal magnitude to the confining axial field. Both fluid current and particle orbits are calculated here in the more interesting regime appropriate to TCS and reactors where the confinement field far exceeds the rotating field strength. New insight is gained into both the flux buildup requirements for two-dimensional equilibria and into the limits on ion rotation in this high conf...
