Abstract

Recently, ELM control experiments have been performed on JET aiming at understanding the plasma response on the magnetic perturbation. Firstly, compensation of the density pump-out effect of perturbation field has been achieved by means of gas fuelling up to a Greenwald fraction of 0.73 in low triangularity plasmas, and by pellets fuelling. Secondly, ELM control has been also carried out in slower rotating plasmas with toroidal field (TF) ripple. A clear difference in the effects on the plasma rotation and density pump-out between TF ripple and EFCC was observed.
