A new experiment has been constructed to study the sustainment of a field-reversed configuration (FRC) with a rotating magnetic field (RMF). FRCs were formed with cold, unmagnetized ions and thus without a kinetic ion component that was believed to provide stability to internal tilt modes. No destructive instabilities were observed for the RMF FRC. Only peripheral radial penetration of the RMF was observed. The radially inward flow arising from axial screening currents at the FRC edge reduced convective and conductive losses to the measurement limit of the diagnostics.
已构建了一项新实验，以研究利用旋转磁场（RMF）维持场反转构型（FRC）的情况。FRC由冷的、未磁化的离子形成，因此没有被认为能为内部倾斜模式提供稳定性的动力学离子成分。对于RMF FRC，未观察到破坏性的不稳定性。仅观察到RMF的周边径向渗透。FRC边缘处轴向屏蔽电流产生的径向向内流动将对流和传导损失降低到了诊断测量的极限。
