TL;DR: In this article, the impact of 3D magnetic perturbations on MHD instabilities, plasma disruptions and plasma turbulence transport in J-TEXT has been investigated, and a new control strategy which applies pulsed RMP to the tearing mode only during the accelerating phase region, was proved by nonlinear numerical modeling to be efficient in accelerating mode rotation and even completely suppresses the mode.

TL;DR: In this article, a series of experiments and simulations of the interaction between resonant magnetic perturbations (RMPs) and plasma were carried out on the J-TEXT tokamak, and the results showed that the m/n = 2/1 (m and n are the poloidal and toroidal mode numbers, respectively) mode locking is obtained with sufficiently large RMPs.

Abstract: The avoidance and suppression of runaway electron (RE) generation during disruptions is of great importance for the safe operation of tokamaks. Massive gas injection is used to suppress the generation of REs, but the poor gas mixing efficiency and extremely high density required to suppress RE generation make the full RE suppression unreliable. The magnetic perturbations provide an alternative RE suppression during disruptions. The use of mode penetration induced by resonant magnetic perturbations (RMPs) to suppress RE generation has been investigated on the J-TEXT tokamak. For a sufficiently long mode penetration duration, robust runaway suppression has been reached during the disruptions. The m/n = 2/1 mode RMP with high amplitude excites large magnetic islands inside the plasma and leads to the large-scale destruction of magnetic surfaces during disruptions, which results in RE loss and runaway-free disruptions. The critical island width required for runaway suppression is estimated to be larger than 0.16 as the minor radius. This value might be slightly underestimated because of the misalignment between the electron cyclotron emission diagnostic and the island O-point. NIMROD simulations are used to investigate the effect of magnetic islands on RE generation during disruption, showing that the large magnetic islands have the ability to enhance RE seed loss during disruptions. RMP can excite large magnetic islands in the target plasma without tearing mode and might be a way to prevent RE generation during disruptions.

TL;DR: In this article, the behavior of runaway currents in massive gas injection (MGI) induced disruptions have been investigated in the J-TEXT tokamak and it was found that the MGI of He or Ne results in runaway free shutdown in a large range of gas injections.
