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.

Academic Significance and Societal Importance of the Research Achievements

核融合研究の大きな目標である原型炉の実現に向けて、成立性のある原型炉設計が求められているが、ELM制御、ダイバータ熱負荷制御として有効な手法を本研究にて発案しその成立性を確認した意義は大きい。
