Sustainment and modification of reversed magnetic shear by LHCD on JT-60U

S Ide, T Fujita, O Naito, M Seki1996年Plasma Physics and Controlled FusionIF 2.2出版社

In the JT-60U tokamak a pre-formed reversed magnetic shear configuration was sustained non-inductively by means of lower hybrid current drive (LHCD). It was formed by neutral beam heating at current build-up and had a reversed shear region extending to 65% of the minor radius. The configuration was sustained for 7.5 s, and the extent of the reversed shear region was kept as large as 55% of the minor radius until the very end. The plasma was stable against MHD activities. It is also demonstrated that LHCD could modify reversed magnetic shear keeping plasma parameters, such as the plasma current and the toroidal magnetic field, the same.

JT-60Uトカマクにおいて、負磁気シア配位が低域混成波電流駆動(LHCD)によって非誘導に維持された。この配位は、電流立ち上げ段階における中性粒子ビーム加熱によって形成され、負磁気シア領域は小半径の65%まで拡がっていた。この配位は7.5秒間維持され、負磁気シア領域の広がりは終了間際まで小半径の55%と大きく保たれた。プラズマはMHD活動に対して安定であった。また、LHCDがプラズマ電流やトロイダル磁場などのプラズマパラメータを同一に保ったまま負磁気シアを修正できることも実証された。
