Low-aspect-ratio stellarators with planar coils

Paul E Moroz1997年Plasma Physics and Controlled FusionIF 2.2出版社

The possibility of using simple sets of planar coils to produce low-aspect-ratio stellarator (LARS) configurations is analysed. Various types of LARS with different planar coils of potential interest to fusion research are identified. It is found that these configurations possess rather attractive features including: compact design and coil simplicity; good access to the plasma; closed vacuum flux surfaces with large enclosed volume; a significant external rotational transform; strong magnetic well; and a natural divertor. Finite plasma-pressure and finite plasma-current effects are studied as well, and it is shown that the LARS configurations considered benefit from the plasma current.

単純な平面コイルのセットを用いて低アスペクト比ステラレータ(LARS)配位を生成する可能性を解析する。核融合研究に有望な様々なタイプの異なる平面コイルを備えたLARSを特定する。これらの配位は、コンパクトな設計とコイルの単純性、プラズマへの良好なアクセス、大きな閉じ込め体積を有する閉じた真空磁気面、大きな外部回転変換、強い磁気井戸、そして自然なダイバータを含む、かなり魅力的な特徴を有することが見出される。有限プラズマ圧力および有限プラズマ電流の効果も研究され、検討されたLARS配位はプラズマ電流から恩恵を受けることが示される。
