通过驱动径向电流穿过托卡马克的外磁表面，在等离子体边缘形成了一个尖锐的输运势垒，并伴随着分叉的极向旋转和径向电场。粒子输运的减少，观察到负径向{italE}场。当径向电流被关闭时，{italE}场和旋转在与离子-离子碰撞时间相当的时间尺度上衰减。
A sharp transport barrier, accompanied by a bifurcated poloidal rotation and a radial electric field, is formed at the plasma edge by driving a radial current across the outer magnetic surfaces of a tokamak. A decrease in particle transport is observed for negative radial {ital E} fields. When the radial current is turned off, the {ital E} field and the rotation damp on a time scale comparable with the ion-ion collision time.
