摘要
为了研究托卡马克等离子体中撕裂模与外加扰动磁场的相互作用机理,J-TEXT托卡马克装置设计安装了静态和动态两套外加扰动场线圈,并开展了一系列扰动场与撕裂模相互作用的实验研究,对具有明显初始撕裂模的等离子体,外加静态扰动磁场可能导致锁模,也可能抑制撕裂模,当等离子体中没有明显的初始撕裂模时,加入较强的静态扰动场将导致撕裂模穿透现象,而利用动态扰动场线圈产生的2/1转动扰动场,观察到了撕裂模磁岛的加速和锁模解锁的现象。实验结果表明,撕裂模与外加扰动场之间作用明显,扰动场是一种很有希望的撕裂模控制手段。
In order to study the interaction of plasma tearing mode and external perturbation magnetic in tokamaks, two sets of resonant magnetic perturbation （RMP） coils which include static RMP coils and dynamic RMP coils have been in- stalled in J-TEXT tokamak and experiments about interaction between RMPs and plasma have been carried out. Static RMP is used to cause mode locking or suppressing with initial tearing mode, RMP penetration occurs without clearly tearing mode when SRMP is strong enough, and 2/1 rotating RMP generated by dynamic RMP coils is applied to accele- rate magnetic island and observe the locked mode unlock. The experimental results demonstrate that the effect of tearing mode and external RMP is evident, thus RMP is a promising method to control the tearing mode.
