Outline of Final Research Achievements

Plasma heating in ITER and DEMO reactors is mainly electron heating by alpha particles generated by fusion reaction. In many devices, including JT-60, electron cyclotron heating (ECH) has been observed to cause degradation of energy confinement and changes in plasma rotation. In this study, we conducted experiments on transport and fluctuations of ECH injection in various magnetic shear discharges of DIII-D device, and clarified under what conditions transport degradation is suppressed. In addition, by comparing the experimental results with the predictions by the theoretical model, an explanation was given as to the cause.

Academic Significance and Societal Importance of the Research Achievements

多くの装置で乱流輸送研究はなされているが、本研究のように高性能プラズマで且つ電子加熱が強い領域での、電子系乱流とイオン系乱流に着目した実験研究はこれまでに例が無く、イオン系及び電子系乱流揺動計測、プラズマ空間分布の時間変化、定常及び非定常輸送解析、局所的及び大域的運動論モデルといった、包括的な研究アプローチをとる本研究を皮切りに、電子加熱時の輸送物理の理解が飛躍的に向上し、乱流シミュレーション・コード開発に貢献すると期待される。検証したモデルにより、より精度の高いプラズマ予測に貢献でき、運転シナリオ開発に貢献できる。
