Abstract
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 installed 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 accelerate 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.
