Recent studies of fast ion transport resulting from a range of instabilities, including n = 1 internal kink modes (fishbones and long-lived modes), toroidal Alfvén eigenmodes and sawteeth have been carried out at MAST. Strong correlations were found between relative changes in magnetic edge coils signals, edge Dα signal a fast ion Dα system, a prototype collimated neutron flux monitor and a recently installed prototype charged fusion product detector array, indicating both redistribution and loss of fast ions. Preliminary interpretation of these observations with a suite of stability, modelling and interpretative codes is discussed.

最近の研究では、多様な不安定性に起因する高速イオン輸送、すなわちn=1内部キンクモード(フィッシュボーンおよび長寿命モード)、トロイダルアルフヴェン固有モード、鋸歯状振動を含む現象について、MASTにおける調査が実施された。磁気エッジ信号の相対変化、エッジDα信号、高速イオンDαシステム、プロトタイプのコリメート中性子束モニター、および最近設置されたプロトタイプの核融合生成物検出器アレイの間には強い相関が認められ、高速イオンの再分布と損失の両方が示唆された。これらの観測結果に対する予備的な解釈は、安定性解析、モデリング、および解釈のための一連のコードを用いて議論される。
