How high is the beta limit for STs? Where is the upper limit for the high-beta ST operation?
Description
High-beta ST research is motivated by its high normalized current Ip/aBT0 achievable at a low aspect ratio and its direct access to second stability for ballooning modes. Key issues for the high-beta ST sustainment are profile control for ballooning/current-driven kink stabilities and positioning of the conductive wall for mode suppression. ST termination by resistive wall modes (RWM) revealed that velocity shear is a useful too for the better stability. (author)
