Effect of three-dimensional conducting structures on vertical stability in EAST

The vertical stability of the Experimental Advanced Superconducting Tokamak (EAST) is studied in detail in the present paper. It is found that correct modelling of the detailed three-dimensional (3D) features of the conducting structures surrounding the plasma is essential in order to get reliable estimates of the growth rate of vertical displacement events. The numerical model developed, based on the CarMa0 code, can take 3D effects into account, and provides results very close to experimental values for a wide range of plasma configurations. A deep insight about the current density patterns induced in passive structures is gained.

本論文では、実験先進超伝導トカマク(EAST)の垂直変位事象の安定性について詳細に検討する。プラズマを取り囲む導体構造物の3次元(3D)的特徴を正確にモデル化することが、垂直変位事象の成長率の信頼性の高い推定を得るために不可欠であることが見出された。CarMa0コードに基づいて開発された数値モデルは、3D効果を考慮することができ、広範囲のプラズマ配位に対して実験値に極めて近い結果を提供する。受動構造物に誘起される電流密度パターンについての深い洞察が得られた。
