A Resonant Magnetic Perturbation (RMP) is an externally-induced small perturbation of the [[MHD equilibrium|equilibrium]] magnetic field, | A Resonant Magnetic Perturbation (RMP) is an externally-induced small perturbation of the [[MHD equilibrium|equilibrium]] magnetic field, | ||
that is resonant with | such that it is resonant with the field at a given magnetic [[flux surface]], | ||
usually | usually located in the plasma edge region. | ||
Resonance means that the perturbation has the same [[Rotational transform|helicity]] as the equilibrium magnetic field at the target flux surface. | |||
The perturbation typically leads to the ergodization of the magentic field around the resonant flux surface. | |||
The goal is to stabilize a specific instability, mainly [[Edge Localized Modes]]. | |||
