Fast-ion transport caused by the combination of MHD and a mock-up test-blanket module (TBM) coil is measured in the DIII-D tokamak. The primary diagnostic is an infrared camera that measures the heat flux on the tiles surrounding the coil. The combined effects of the TBM and four other potential sources of transport are studied: neoclassical tearing modes, Alfén eigenmodes, sawteeth, and applied resonant magnetic perturbation fields for the control of edge localized modes. A definitive synergistic effect is observed at sawtooth crashes where, in the presence of the TBM, the localized heat flux at a burst increases from to MW m−2.

高速イオン輸送は、DIII-Dトカマクにおいて、MHDとモックアップ試験ブランケットモジュール(TBM)の組み合わせによって引き起こされる現象として測定される。主たる診断装置は赤外線カメラであり、TBMを取り囲むタイル上の熱流束を測定する。TBMと、新古典テアリングモード、アルヴェン固有モード、鋸歯状振動、および周辺局在モード(ELM)の制御のための共鳴磁場摂動という4つの他の潜在的な輸送源の複合的な影響が研究される。鋸歯状振動のクラッシュ時には、TBMの存在下で局所的な熱流束が から MW m−2 へと増加するという、明確な相乗効果が観測される。
