 note = {We report a numerical study of locked modes (LMs) in tokamaks, which demonstrates active control of LMs via rotating magnetic perturbations. We have developed the resistive MHD simulation code “AEOLUS-IT”, which can simulate the LM, where the magnetic island interacts with rotating and/or static external magnetic perturbations, under JT-60SA class high magnetic Reynolds number condition. The developed code successfully simulates the stabilization effect of the rotating magnetic perturbation against the static magnetic perturbation, which reveals a frequency dependence of the rotating magnetic perturbation for suppressing the island evolution. Furthermore, dependencies of mode behavior on frequency and polarity of the rotating magnetic perturbation are explored in detail, which reveals the optimum frequency and polarity of the rotating magnetic perturbation to control the LM. Here, the rotational direction of the rotating magnetic perturbation to the equilibrium plasma rotation in the laboratory frame is referred to as ‘polarity’. The rotating magnetic perturbation acts on the background rotating plasma in the presence of a static field. Under such circumstances, there exist bifurcated states of the background rotating plasma, which should be taken into account when studying the dependence of the mode behavior on the rotating magnetic perturbation., Plasma Conference 2017},
