Abstract

Dynamic mitigation for the tearing mode instability in the current sheet in collisionless plasmas is demonstrated by applying a wobbling electron current beam. The initial small amplitude modulations imposed on the current sheet induce the electric current filamentation and the reconnection of the magnetic field lines. When the wobbling or oscillatory motion is added from the electron beam having a form of a thin layer moving along the current sheet, the perturbation phase is mixed and consequently the instability growth is saturated remarkably, like in the case of the feed-forward control.

摘要

通过应用摆动电子束，证明了无碰撞等离子体电流片中撕裂模不稳定性的动态缓解。施加在电流片上的初始小振幅调制会引发电流丝化和磁力线重连。当沿着电流片移动的薄层形式的电子束添加摆动或振荡运动时，扰动相位会混合，因此不稳定性增长会显著饱和，类似于前馈控制的情况。
