Effects of ICRF waves to EAST LHCD discharges on intrinsic rotations

Ion cyclotron range of frequencies (ICRFs) have proven to efficiently serve as a toroidal rotation source in tokamak plasmas. Recent experiments on the experimental advanced superconducting tokamak show that the rotation profiles are remarkably modified when the internal inductance (li) changed. The comparisons of the ion and electron temperature profiles among ICRF-heated plasmas suggest that the change in li can remarkably affect the toroidal rotation velocity. The scaling of rotation velocity increments as a function of the change in li also suggests that ICRF would serve as a reliable rotation source in plasmas with larger li decrements.

イオンサイクロトロン周波数帯(ICRF)は、トカマクプラズマにおいて環状回転源として効率的に機能することが実証されている。実験先進超伝導トカマク(EAST)での最近の実験は、内部インダクタンス(li)が変化すると回転分布が顕著に変化することを示している。ICRF加熱プラズマにおけるイオンおよび電子温度分布の比較は、liの変化が環状回転速度に顕著に影響を与える可能性を示唆している。回転速度増分のli変化に対するスケーリングは、ICRFがより大きなli減少を伴うプラズマにおいて信頼性の高い回転源となることを示唆している。
