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: Wang et al. as discussed by the authors calculated the parallel residual stress and parallel turbulent acceleration driven by electrostatic collisionless trapped electron mode (CTEM) turbulence using gyrokinetic theory.

TL;DR: In this paper, the authors proposed a new mechanism named turbulent acceleration for the origin of the intrinsic parallel rotation based on gyrokinetic theory, which acts as a local source or sink of parallel rotation, which is different from the divergence of residual stress, i.e., surface force.

TL;DR: In this article, it is proved that the electromagnetic turbulent acceleration as a candidate for intrinsic parallel flow generation driven by pressure gradient along the total magnetic field line does not contradict the momentum conservation.
