旋转马克是一种紧凑的球形磁约束装置。在旋转马克中，等离子体电流是由旋转磁场驱动的。驱动电流可以使原有的平衡场反转，产生场反转结构。在传统的旋转马克中，环形场（TF）不需要RMF驱动等离子体电流，但发现额外的TF的存在会影响RMF电流的驱动。本文较详细地研究了转矩转矩对旋转发动机中转矩转矩电流驱动的影响。实验结果表明，TF的加入大大增加了RMF驱动电流，显著提高了RMF的穿深。没有TF， RMF只能在边缘区域穿透等离子体。当加入TF时，RMF几乎可以到达整个等离子体区域。当Bv和射频发生器功率固定时，这是获得最大等离子体电流的最佳环向磁场强度。除了驱动电流外，RMF还在旋转马克等离子体中产生高谐波场。本文还报道了TF对谐波谱的影响。
A rotamak is one kind of compact spherically shaped magnetic-confinement device. In a rotamak the plasma current is driven by means of rotating magnetic field (RMF). The driven current can reverse the original equilibrium field and generate a field-reversed-configuration. In a conventional rotamak, a toroidal field (TF) is not necessary for the RMF to drive plasma current, but it was found that the present of an additional TF can influence the RMF current drive. In this paper the effect of TF on the RMF current drive in a rotamak are investigated in some detail. The experimental results show that addition of TF increases the RMF driven current greatly and enhances the RMF penetration dramatically. Without TF, the RMF can only penetrate into plasma in the edge region. When a TF is added, the RMF can reach almost the whole plasma region. This is an optimal strength of toroidal magnetic field for getting maximum plasma current when Bv and radio frequency generator power are fixed. Besides driving current, the RMF generates high harmonic fields in rotamak plasma. The effect of TF on the harmonic field spectra are also reported.
