Dedicated experiments were conducted in mixed H-D plasmas in JET to demonstrate the efficiency of the 3-ion ICRF scenario for plasma heating, relying on injected fast NBI ions as the resonant ion component. Strong core localization of the RF power deposition in the close vicinity of the ion-ion hybrid layer was achieved, resulting in an efficient plasma heating, generation of energetic D ions, strong enhancement of the neutron rate and observation of Alfvénic modes. A consistent physical picture that emerged from a range of fast-ion measurements at JET, including neutron and gamma-ray measurements, a high-energy neutral particle analyzer and MHD mode localization analysis, is presented. The possibility to moderate the fast-ion energies with the ratio PICRF/PNBI and the choice of the NBI injectors is demonstrated. An outlook of possible applications of the 3-ion scenarios, including a recent example of its use in mixed D-3He plasmas in JET and promising scenarios for D-T plasmas, are presented.

混合H-DプラズマにおけるJETでの専用実験を実施し、共鳴イオン成分として注入された高速NBIイオンに依存する3イオンICRFシナリオのプラズマ加熱効率を実証した。イオン-イオン混成層のごく近傍におけるRF出力堆積の強いコア局在化を達成し、その結果、効率的なプラズマ加熱、高エネルギーのDイオンの生成、中性子率の大幅な増強、およびアルフヴェン波モードの観測がもたらされた。JETにおける一連の高速イオン計測(中性子およびガンマ線計測、高エネルギー中性粒子分析装置、MHDモード局在解析を含む)から得られた一貫した物理的描像を示す。PICRF/PNBI比とNBI入射器の選択により高速イオンエネルギーを調整できる可能性を実証する。3イオンシナリオの可能な応用に関する展望として、JETにおける混合D-3Heプラズマでの最近の使用例や、D-Tプラズマに対する有望なシナリオを示す。
