A high ion temperature discharge in the lower hybrid current drive scheme has been obtained for the first time in the world in the TRIAM-1M superconducting tokamak. The high ion temperature mode is triggered by a transition which occurs within an operation window for the density, horizontal plasma position and antenna phasing. A steep ion temperature gradient (>80 keV/m) is formed near the core region at the transition. Long duration operation of this discharge has beensuccessfully demonstrated in both the limiter and single null configurations by multiple controltechniques.

下部混合電流駆動方式における高イオン温度放電が、TRIAM-1M超伝導トカマクにおいて世界で初めて達成された。高イオン温度モードは、密度、水平プラズマ位置、およびアンテナ位相に関する動作ウィンドウ内で発生する遷移によって引き起こされる。急峻なイオン温度勾配(>80 keV/m)が、遷移時にコア領域近傍で形成される。この放電の長時間運転は、リミター配置およびシングルヌル配置の両方において、複数の制御技術により実証に成功した。
