Research Abstract

本研究は,大きな成果を上げることができた,ローカルアイランドダイバータ(LID)を用いた周辺プラズマ制御研究で得られた知見を,エルゴディック層を有する閉構造ダイバータによる制御に発展させ,核融合の実現に必要な高温・高密度プラズマの更なる高性能化(閉じ込め性能の向上)を目的としている.また,トーラス装置に共通と考えられる閉じ込め改善のメカニズムを解明し,閉構造ダイバータが具備すべき物理要素を確定し,将来の核融合炉設計に貢献する.
具体的には,エルゴディック層を有する閉構造ダイバータが,LIDと同等以上のダイバータ機能を有するか否かを,中性粒子および不純物の制御性,ペレットによる中心燃料粒子供給との整合性,密度および温度分布の制御性等に着目した実験で明らかにする.
