Energy and particle transport in plasmas with transport barriers

V V Parail2002年Plasma Physics and Controlled FusionIF 2.2出版社

Up to five regions with different transport properties can be identified in tokamak plasma with edge and internal transport barriers. This includes edge and core barriers, the region near the separatrix, which is dominated by atomic physics, the core plasma (within 0.4⩽ρ⩽0.8, where ρ is a normalized minor radius) and the central part of plasma volume, which is often dominated by large-scale MHD phenomena. An overview of the present understanding of heat and particle transport in these five regions will be given, which includes progress in experimental observations, theory of plasma microturbulence and predictive modelling.

トカマクプラズマにおいて、エッジおよび内部輸送障壁を有する場合、輸送特性の異なる最大5つの領域を特定できる。これには、エッジ障壁とコア障壁、セパラトリクス近傍の領域(原子物理が支配的)、コアプラズマ(0.4⩽ρ⩽0.8、ここでρは規格化小半径)、およびプラズマ体積の中心部(しばしば大規模MHD現象が支配的)が含まれる。これら5つの領域における熱および粒子輸送に関する現在の理解の概要を示す。これには、実験的観測の進展、プラズマ微視的不安定性の理論、および予測モデリングが含まれる。
