Tight aspect ratio Tokamaks-theory and experiment

The START (Small Tight Aspect Ratio Tokamak) experiment became operational in January 1991 at AEA Fusion Culham Laboratory. It is the only tokamak producing hot plasmas at aspect ratios as low as A=R/a approximately 1.3, and is providing valuable insight into the physical processes (such as toroidicity and trapping) involved at low aspect ratio. Three topics are discussed: equilibrium properties, including evidence of neo-classical and bootstrap effects; energy confinement studies; and MHD properties, including possible explanations for the apparent absence of the major disruption at low A.

START(Small Tight Aspect Ratio Tokamak)実験は、1991年1月にAEA Fusion Culham研究所で運転を開始した。これは、アスペクト比がA=R/a≈1.3という低い値で高温プラズマを生成する唯一のトカマクであり、低アスペクト比における物理過程(トロイダル性や捕捉粒子効果など)について貴重な知見を提供している。本論文では、以下の3つのテーマについて論じる:新古典効果やブートストラップ効果の証拠を含む平衡特性、エネルギー閉じ込め研究、および低Aにおける主要ディスラプションの不在に対する可能な説明を含むMHD特性。
