Operational limits of ASDEX Upgrade H mode discharges in the new closed Divertor II configuration

Systematic investigations of gas fuelled, high density H mode discharges with the new closed Divertor II of ASDEX Upgrade are reported. The focus is on operational limits (H-L transition, density limit) over a wide range of externally controllable plasma parameters. It is found that the H mode threshold power dramatically exceeds the generally accepted prediction Pthreshheat ∝ eBt when high densities are approached. Highest densities (density limit) are achieved close to the H-L mode back-transition and are generally associated with complete divertor detachment. The scaling of the density limit is assessed and discussed with a view to detachment based models and the Greenwaldlimit.

新しい閉ダイバータIIを備えたASDEX Upgradeにおいて、ガス入射高密度Hモード放電の系統的調査について報告する。焦点は、広範囲の外部制御可能なプラズマパラメータにおける動作限界(H-L遷移、密度限界)に置かれる。高密度に近づくと、Hモード閾値パワーが一般に受け入れられている予測Pthreshheat ∝ eBtを劇的に上回ることが見出された。最高密度(密度限界)はH-Lモード逆遷移に近いところで達成され、一般に完全なダイバータデタッチメントを伴う。密度限界のスケーリングを評価し、デタッチメントに基づくモデルとグリーンワルド限界の観点から考察する。
