Conditions and benefits of X-point radiation for the island divertor

Nuclear Fusion
We present a method to geometrically quantify the three magnetic island chains with the poloidal mode numbers m = 4, 5, and 6 (referred to in this paper as high-iota, standard, and low-iota islands, respectively), on which the W7-X divertor relies.

Improved weighted sum estimation of total radiated power at W7-X

Nuclear Fusion
As magnetic confinement devices move toward higher fusion powers, moderating the heat load to the plasma-facing components becomes increasingly challenging. Efficient power dissipation can be achieved through control of the plasma radiation.

EMC3-EIRENE コードを用いた JT-60SA 周辺プラズマモデリング

EMC3-EIRENE コードを用いた JT-60SA 周辺プラズマモデリング
ELM 制御における外部共鳴摂動磁場（RMP）の有効性が多くの核融合実験装置で確認されたことから、原型炉を含む将来の装置への適用の検討が始まっている。新たな装置設計には計算機シミュレーションによる予測が不可欠である、３次元性を有する RMP を取り込んだ周辺プラズマシミュレーション研究は十分でない。応募者らは今年度より、近々運転の開始される JT-60SA を対象とし、３次元輸送コード EMC3-EIRENE による周辺プラズマモデリング研究を開始した。講演では、軸対称グリッドの作成と初期的な計算結果を述べ、２次元輸送コード SONIC との比較計算の進捗について発表する。将来的には、RMP を取り込んだ非軸対称グリッドでの３次元計算ならびに実験との比較 ...
