Abstract

MHD and plasmoids are key elements in pellet injection experiments on FTU. The plasmoid drift can take particles from the pellet ablation region to the q=1 surface in high field side (HFS) pellet injection on FTU. Then MHD reconnections could take density from that region to the plasma center. A strong MHD event would be triggered by the injected pellet in high current (1.1 MA) discharges. A preliminary comparison between the post-pellet experimental density profile in low current discharges (0.8 MA) and the result of a pellet ablation code is presented. Strong magnetic fluctuations develop during pellet ablation. They may be Alfvén waves generated by the drifting plasmoids, preliminary results are shown.
