Transport analysis during the transient phase of heating (a dynamic transport study) applied to the plasma with internal transport barriers (ITBs) in the Large Helical Device (LHD) heliotron and the JT-60U tokamak is described. In the dynamic transport study the time of transition from the L-mode plasma to the ITB plasma is clearly determined by the onset of flattening of the temperature profile in the core region and a spontaneous phase transition from a zero curvature ITB (hyperbolic tangent shaped ITB) or a positive curvature ITB (concaved shaped ITB) to a negative curvature ITB (convex shaped ITB) and its back-transition are observed. The flattening of the core region of the ITB transition and the back-transition between a zero curvature ITB and a convex ITB suggest the strong interaction of turbulent transport in space.

大型ヘリカル装置(LHD)ヘリオトロンおよびJT-60Uトカマクにおける内部輸送障壁(ITB)を有するプラズマに適用した、加熱の過渡期における輸送解析(動的輸送研究)について述べる。動的輸送研究において、LモードプラズマからITBプラズマへの遷移時刻は、コア領域における温度分布の平坦化の開始によって明確に決定される。また、ゼロ曲率ITB(双曲線正接型ITB)または正曲率ITB(凹型ITB)から負曲率ITB(凸型ITB)への自発的相転移と、その逆遷移が観測される。ITB遷移におけるコア領域の平坦化、およびゼロ曲率ITBと凸型ITB間の逆遷移は、空間における乱流輸送の強い相互作用を示唆している。
