| Outline of Final Research Achievements |
Reduction of heat load and erosion of the diverter plate is one of the most important issues for the research & development of tokamak fusion reactors. The edge localized mode (ELM) in H-mode operation is especially to be suppressed. Although suppression of ELM by the resonant magnetic perturbation (RMP) has been experimentally demonstrated, it is difficult to apply the RMP coils to the DEMO-reactor circumstance with strong neutron flux. Here we showed that the RMP is easily generated in a tokamak reactor by an innovative method to install the ferritic steel helically. For the study of edge plasmas under RMP we developed simulation models and codes. We also presented new diverter configurations to reduce the diverter heat load after the ELM suppression.
