报告摘要:

Promising control of Edge Localized Mode (ELM) and divertor heat fluxusing various toroidal harmonics of Resonant Magnetic Perturbations (RMPs) and the combination of them in Radio Frequency (RF) waves dominant heating plasmashave been demonstrated in the EAST tokamak. EAST is a unique tokamak aiming forachieving steady state long pulse operation with RF dominant heating and ITERlike tungsten divertor. A flexible in-vessel RMP coil system was applied for ELM and divertor flux control in EAST. Significant progresses have been made inaccessing full ELM suppression using variety form of RMPs in different operational windows in EAST. Progresses in understanding the linear and nonlinear plasma response on ELM suppression and related 3D physics have been made in EAST. These results expand physics understanding and potential effectiveness of RMP for reliably controlling ELMs and divertor heat/particle loading distributions in future burning plasma devices such as ITER.
