Abstract
Abstract In order to develop a new alternative magnetic diverted (AMD) discharge on EAST, it is necessary to define a series of target configuration parameters on plasma control system (PCS), especially this new configuration requires a strong effort on the poloidal field (PF) coil currents. By combining the static equilibrium configuration optimization and flux consuming estimation for PF coils current, multiple basic scenarios with exactly the same target configuration were designed for different stages on plasma current flat-top phase. The high PF coil currents requirement was optimized by the specific equilibrium design procedure to keep them away from the limitation. In this paper, we present the fast scenario design details, together with the experiments results.
