ELM mitigation via rotating resonant magnetic perturbations on MAST

A.J. Thornton, A. Kirk, P. Cahyna, I.T. Chapman, more

Journal of Nuclear Materials > 2015 > 463 > C > 723-726

The application of resonant magnetic perturbations (RMPs) produces splitting of the divertor strike point due to the interaction of the RMP field and the plasma field. The application of a rotating RMP field causes the strike point splitting to rotate, distributing the particle and heat flux evenly over the divertor. The RMP coils in MAST have been used to generate a rotating perturbation with a toroidal...
