Effect of Toroidal Field Ripple on Fast Ion Behavior in a Tokamak

概要

論文の詳細を見る
Computational studies have been performed for fast ton behavior in a Tokamakwith toroidal field rir>rle. Collisionless behavior of fast tons relating to ripple..trapping, ripple-detrapping and banana drift is of essential importance in fastion loss processes in case of quasi-perpendicular neutral beam injection. Thecollisionless ripple trapping and ripple-enhanced banana drift produce a largenumber of loss bands in velocity space and enhance the loss of fast tons. Thefast ion loss associated with ripple can be categorized into two groups; ripple-trapped loss and banana-drift loss. The amount of loss particles due to the respec-tive loss process is significantly influenced by the effect of finite banana size offast ions. The ripple-trapped loss particles are localized in a specific region on thefirst wall surface.
