摘要/Abstract

摘要： The major disruption limits the operation of present tokamaks．Experimental evidences point out that the growth of tearing modes or the magnetic islands is primarily responsible for the occurrence．Taking the non-inductive current drive effects into account, a set of 3D nonlinear equation is derived．It is shown from simulation that the growth of the magnetic island is suppressed effectively by RF current drive．It is consistent with recent experiments on the HL-1tokamak in which the plasma is stabilized by an RF current drive．
