Tailoring resonant magnetic perturbation to optimize fast-ion confinement during ELM control in KSTAR

Nuclear Fusion, 2023
3D resonant magnetic perturbation (RMP) is one promising way to control edge localized modes that can cause excessive material erosion of tokamak first walls.

Plasma response impact on RMP divertor footprint modeling for KSTAR

Nuclear Materials and Energy, 2023
The striation pattern of heat loads on the divertor targets is determined by the plasma response to external resonant magnetic perturbations (RMPs) applied for suppression of edge localized modes (ELMs).

Progress towards edge-localized mode suppression via magnetic perturbations in hydrogen plasmas

Nuclear Fusion
The suppression of edge-localized modes (ELMs) by applying resonant magnetic perturbations (RMPs) is well studied in low collisionality deuterium plasmas as a measure to reduce transient divertor heat loads.

ELM Suppression by Boron Powder Injection and Comparison with Lithium Powder Injection on EAST

Journal of Fusion Energy, 2020
Type I edge-localized modes (ELMs) in the Experimental Advanced Superconducting Tokamak (EAST) were completely suppressed via boron powder injection into the X-point region of an upper-single null configuration over a wide range of operating conditions (2.8

Application of non-integer-n RMP coil current waveform for ELM control in JA DEMO

Nuclear Fusion
We have studied the resonant magnetic perturbation (RMP) coil concept for edge localized mode (ELM) suppression in JA DEMO, a design concept of a steady-state tokamak demonstration reactor, based on the vacuum magnetic model.

Influence of n = 4 RMPs on pedestal structure and stability in EAST

Nuclear Fusion
Changes of pedestal structure and stability caused by n = 4 resonant magnetic perturbations (RMPs) for control of Edge Localized Modes (ELMs) in the EAST tokamak in a target plasma close to the ITER high- Q scenario are studied in this paper.

Density compensation with pellet fueling during ELM suppression with n = 4 RMP on metal-wall EAST tokamak

Nuclear Materials and Energy
Pellet injection is the most promising fueling method to achieve a deep particle deposition for future fusion reactors. On metal-wall EAST tokamak, a full density compensation has been achieved by the pellet fueling during ELM suppression with n = 4 RMP ...

The Relationships Between ELM Suppression, Pedestal Profiles, and Lithium Wall Coatings in NSTX [PDF]

, 2011
Recently in the National Spherical Torus Experiment (NSTX), increasing lithium wall coatings suppressed edge localized modes (ELMs), gradually but not quite monotonically. This work details profile and stability analysis as ELMs disappeared throughout the lithium scan.
