| Outline of Final Research Achievements |
We have developed an advanced control method as “Toroidal field modulation” for edge localized mode (ELM) that could induce unacceptable heat load to divertor target. To validate applicability of this method to DEMO design, magnetic field line tracing, fast ion analysis and mechanical analysis were conducted. These analysis results show that the TFM can produce enough stochastization of edge region for ELM control without a degradation of the fast ion confinement, and the electromagnetic force analysis shows the TFM does not have any serious issues from the engineering points of view. Furthermore, the perturbation coil that can induce dynamic heat load control using rotating field and has applicability to error filed correction as well, is proposed and confirmed to be available in DEMO.
