A summary is given on recent experiments in L-mode with ion cyclotron resonance heating (ICRH) of hydrogen minority in deuterium plasmas on EAST. Experiments show a degradation of confinement with increasing power. Furthermore, the energy confinement time increases with plasma current and magnetic field, whereas it is insensitive to line averaged density. Minority heating has been found to be efficient, and parameters were optimized to maximize its efficiency. ICRH in lower hybrid waves heated plasma was also investigated.

要約:EASTにおける重水素プラズマ中の水素マイノリティを用いたイオンサイクロトロン共鳴加熱(ICRH)に関する最近の実験について概説する。実験により、加熱パワーの増大に伴う閉じ込めの劣化が示された。さらに、エネルギー閉じ込め時間はプラズマ電流および磁場とともに増加する一方、線平均密度には依存しないことが明らかになった。マイノリティ加熱は効率的であることが見出され、その効率を最大化するためのパラメータ最適化が行われた。また、低混成波加熱プラズマにおけるICRHについても調査された。
