Internal Helical Mode M = 1 of a Tokamak in the Plateau and Banana Regimes

摘要

The internal helical mode m = 1 of a tokamak in the plateau and banana regimes was investigated theoretically. It was demonstrated that in the plateau regime the increment of this mode is as small as a/R (a and R are the small and large radii of the torus) as compared with the predicted MHD value. With the transition from the plateau regime to the banana regime the increment increases, approaching the standard MHD value. (ERA citation 09:042424)
