Model for improved divertor confinement

G.M. Staebler1990年被引用 4Nuclear FusionIF 3出版社

The improved divertor confinement (IDC) phenomenon, observed in the JT-60 tokamak, is explained using collisional transport theory. The model successfully describes the correlation between the increase in radiated power at the divertor and the increase in line averaged density of the plasma, which is characteristic of the IDC. Other prominent features of IDC, such as the grad-B drift dependence, divertor heat flux asymmetries and carbon-oxygen impurity exchange, are also explained. The model predicts that IDC could be obtained in deuterium plasmas. The reduction in heat load to the divertor caused by IDC would be an important benefit for a fusion reactor.

改善されたダイバータ閉じ込め(IDC)現象は、JT-60トカマクで観測され、衝突輸送理論を用いて説明される。このモデルは、ダイバータにおける放射パワーの増加とプラズマの線平均密度の増加との間の相関を首尾よく記述しており、これはIDCの特徴である。grad-Bドリフト依存性、ダイバータ熱流束の非対称性、炭素-酸素不純物交換など、IDCの他の顕著な特徴も説明される。このモデルは、IDCが重水素プラズマにおいて達成され得ることを予測する。IDCによって引き起こされるダイバータへの熱負荷の低減は、核融合炉にとって重要な利点となるであろう。
