Results are presented of the first Lower Hybrid Current Drive (LHCD) experiments in JT-60. 2 MA of RF driven current is successfully produced for the first time in a reactor grade tokamak. The magnetic divertor works quite well in eliminating the impurities released by the current carrying fast electrons which have allowed the generation of the reactor relevant RF current in a very low density plasma. The efficiency which is defined as ηCD = eRIRF/PLH(1019 m−3 A·W−1), reaches values of 0.8 to 1.7. NBI heating enhances the current drive efficiency by a factor of 1.5, and LHCD improves the confinement time of high power NBI heated plasma. The key to confinement improvement is found to be the active control of the current profile by LHCD.

JT-60における最初の低ハイブリッド電流駆動(LHCD)実験の結果を提示する。炉心級トカマクにおいて、2 MAのRF駆動電流の生成に初めて成功した。磁気ダイバータは、非常に低密度プラズマ中で炉心級のRF電流を生成する高速電子によって放出される不純物を除去する上で、極めて良好に機能した。効率ηCD = eRIRF/PLH(1019 m−3 A·W−1)は0.8から1.7の値を達成した。NBI加熱は電流駆動効率を向上させ、LHCDは高パワーNBI加熱プラズマの閉じ込め時間を改善した。閉じ込め改善の鍵は、LHCDによる電流分布の能動的な制御にあることが見出された。
