Resonant magnetic perturbations
Non-axisymmetric magnetic fields used to control tokamak edge instabilities
From Wikipedia, the free encyclopedia
Resonant magnetic perturbations (RMPs) are a special type of magnetic field perturbations used to control burning plasma instabilities called edge-localized modes (ELMs) in magnetic fusion devices such as tokamaks. The efficiency of RMPs for controlling ELMs was first demonstrated on the tokamak DIII-D in 2003.[1]
Normally the rippled magnetic field will only suppress ELMs for very narrow ranges of the plasma current.[2]
