Effect of passive structure and toroidal rotation on resistive wall mode stability in the EAST tokamak

doi:10.1088/1674-1056/23/7/075205

Abstract If β_N exceeds β_N^no-wall, the plasma will be unstable because of external kink and resistive wall mode (RWM). In this article, the effect of the passive structure and the toroidal rotation on the RWM stability in the experimental advanced superconducting tokamak (EAST) are simulated with CHEASE and MARS codes. A model using a one-dimensional (1D) surface to present the effect of the passive plate is proved to be credible. The no wall β_N limit is about 3l_i, and the ideal wall β_N limit is about 4.5l_i on EAST. It is found that the rotation near the q=2 surface and the plasma edge affects the RWM more.
