Parametric instabilities, which bring about undesirable peripheral heat deposition in lower-hybrid-wave (LHW) heating, are stabilized in the JFT-2 tokamak by an effective electron heating in the boundary plasma. The boundary electron temperature rises significantly by simultaneous injection of neutral beams into the plasma, which may be expected to improve the heating efficiency of LHW in the main plasma

下ハイブリッド波(LHW)加熱における望ましくない周辺部での熱堆積をもたらすパラメトリック不安定性は、JFT-2トカマクにおいて、境界プラズマ中の効果的な電子加熱によって安定化される。境界電子温度は、プラズマへの中性ビームの同時入射によって有意に上昇し、これにより主プラズマにおけるLHWの加熱効率の向上が期待される。
