Edge localized modes control by resonant magnetic perturbations

Journal of Nuclear Materials, 2007
A number of designs for external or in-vessel coils generating Resonant Magnetic Perturbations (RMPs) for type I ELMs control in ITER are analyzed. The RMPs generated by the I-coils in the successful DIII-D ELMs control experiments are taken as a reference. The three ITER characteristic scenarios (H-mode, hybrid and steady-state) are studied.

ELM suppression by resonant magnetic perturbations at DIII-D

2009 23rd IEEE/NPSS Symposium on Fusion Engineering, 2009
Edge localized mode (ELM) suppression by resonant magnetic perturbations (RMPs) is being studied at DIII-D with ITER-similar plasma shapes and edge collisionalities. Suppression at low collisionality correlates with overlap of vacuum magnetic field islands in a quantified edge layer at moderate q.

Influence of resonance magnetic perturbation on the asymmetric magnetic perturbation induced double tearing modes

Radiation Effects and Defects in Solids, 2021
In this paper, we have studied the influence of resonance magnetic perturbation (RMP) on the double tearing modes induced by asymmetric magnetic perturbation in a 2D geometry based on the MHD model...

Magnetic Island Formation in Coexisting System of Resonant Magnetic Perturbation and Perturbed Bootstrap Current

Journal of the Physical Society of Japan, 2019
A reduced two-fluid model describing the coexisting system of the resonant magnetic perturbations (RMPs) and plasma flows is extended to include an effect of the perturbed bootstrap current.

Screening of resonant magnetic perturbations by flows in tokamaks

Nuclear Fusion, 2012
Abstract The non-linear reduced four-field RMHD model in cylindrical geometry was extended to include plasma rotation, neoclassical poloidal viscosity and two fluid diamagnetic effects. Interaction of the static resonant magnetic perturbations (RMPs) with the rotating plasmas in tokamaks was studied.

The interaction of resonant magnetic perturbations with rotating plasmas

Physics of Fluids B: Plasma Physics, 1991
The penetration of a helical magnetic perturbation into a rotating tokamak plasma is investigated. In the linear regime, it is found that unless the frequency of the imposed perturbation matches closely to one of the natural mode frequencies, reconnection at the rational surface is suppressed by a large factor.

Shielding of resonant magnetic perturbations by rotation

Physics of Plasmas, 1996
Magnetic perturbations that drive islands are shielded from a rotating plasma by either a torque limit or an equilibrium limit. The physics of the shielding is given in a simple slab model along with the mechanism by which the shielding currents are maintained.
