ELM suppression in helium plasmas with 3D magnetic fields
Nuclear Fusion, 2017 Experiments in DIII-D, using non-axisymmetric magnetic perturbation fields in high-purity low toroidal rotation, He-4 plasmas have resulted in Type-I edge localized mode (ELM) suppression and mitigation. Suppression is obtained in plasmas with zero net input torque near the L-H power threshold using either electron cyclotron resonant heating (ECRH) or ...

Observation of a multimode plasma response and its relationship to density pumpout and edge-localized mode suppression [PDF]
, 2015 Density pumpout and edge-localized mode (ELM) suppression by applied n=2 magnetic fields in low-collisionality DIII-D plasmas are shown to be correlated with the magnitude of the plasma response driven on the high-field side (HFS) of the magnetic axis ...

Argon–seeded detachment during ELM control by RMPs in KSTAR
Nuclear Fusion, 2023 In this study, we demonstrate argon-seeded discharges that exhibited a detached divertor during the full suppression and mitigation of edge-localized modes (ELMs) by an International Thermonuclear Experimental Reactor-like, three-row resonant magnetic ...

Edge stability of stationary ELM-suppressed regimes on DIII-D
Journal of Physics: Conference Series, 2008 We discuss the MHD stability of the H-mode pedestal region in two edge localized mode (ELM)-suppressed H-mode regimes on DIII-D, the quiescent (Q)H-mode and resonant magnetic perturbation (RMP) H-mode. The QH-mode is obtained at low density with most of the neutral beam power injected counter to the plasma current, and is characterized by a continuous,

Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls [PDF]
, 2019 This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another (pulse 92432) from after the installation of JET's ITER-like Wall (ILW ...
