螺旋磁限制器在极向和环向方向的旋转被证明是一个很好的方法，避免不均匀的壁加载时，得到一个静态的局部螺旋场被施加。从磁场结构、双极性、电子沿随机磁场的沿着输运和等离子体粒子的跨场漂移运动等方面讨论了托卡马克边缘等离子体势的静态和动态修正机制。的磁结构进行了研究庞加莱映射的场线追踪数值，使用代码，占当地螺旋线圈的确切配置。
Rotation of a helical magnetic limiter in the poloidal and toroidal directions is shown to be a good method of avoiding the non-uniform wall loading that is obtained when a static local helical field is applied. Mechanisms of the static and dynamic modification of the plasma potential at the tokamak edge are discussed in terms of magnetic field structure, ambipolarity, electron transport along the stochastic magnetic fields and cross-field drift motion of plasma particles. The magnetic structure is studied by Poincaré mapping of field lines traced numerically, using a code that accounts for the exact configuration of local helical coils.
