Reduction of sawtooth amplitude by resonant magnetic perturbation [PDF]
Nuclear Fusion, 2020 Sawtooth crashes of large amplitude are detrimental to tokamak plasma confinement, and the amplitude has to be reduced for a fusion reactor. A novel method, i.e.

Suppressing magnetic island growth by resonant magnetic perturbation [PDF]
Nuclear Fusion, 2018 The effect of externally applied resonant magnetic perturbations (RMPs) on the growth of magnetic islands is investigated based on two-fluid equations. It is found that if the local bi-normal electron fluid velocity at the resonant surface is sufficiently large, static RMPs of the same helicity and of moderate amplitude can suppress the growth of ...

Direct effects of the resonant magnetic perturbation on turbulent transport [PDF]
Nuclear Fusion, 2016 Abstract The effects of the resonant magnetic perturbations (RMPs) on the turbulent transport are analyzed in the framework of the test particle approach using a semi-analytical method. The model includes particle collisions. The influence of the RMPs on plasma confinement is determined as function turbulence parameters and of ...

Stochastic fluctuation and transport of tokamak edge plasmas with the resonant magnetic perturbation field [PDF]
Physics of Plasmas, 2021 We present that a statistical method known as the complexity–entropy analysis is useful to characterize a state of plasma turbulence and flux in the resonant magnetic perturbation (RMP) edge localized mode (ELM) control experiment.

Pedestal collapse by resonant magnetic perturbations
Nuclear Fusion, 2021 Abstract Pedestal collapse (i.e., the complete loss of the edge transport barrier (ETB)) in DIII-D H-mode plasmas occurs when resonant magnetic perturbations (RMPs) penetrate the steep gradient region at the plasma edge. Normally, RMP driven magnetic islands can occur at the top and bottom of the H-mode pedestal and these islands ...
