On the role of the edge density profile for the L–H transition power threshold in ASDEX Upgrade

The L–H transition power threshold () in full tungsten (W) wall discharges is lower by 25% compared to those with graphite (C) mix tungsten walls in ASDEX Upgrade (Ryter et al 2013 Nucl. Fusion53113003). The lower power threshold in the full tungsten wall discharges has been found to correlate with higher edge density as well as steeper edge density gradient. An estimate of the minimum in the neoclassical radial electric field well inside the separatrix yields a constant value for all analyzed L–H transitions at fixed toroidal magnetic field (). The decrease of the threshold power is explained by the steeper edge density gradient in the discharges with full tungsten wall.

L-H遷移パワー閾値()は、グラファイト(C)とタングステン(W)の混合壁を有するASDEX Upgrade(Ryterら 2013 Nucl. Fusion 53 113004)と比較して、全タングステン壁放電において25%低い。全タングステン壁放電におけるパワー閾値の低下は、より高い周辺密度およびより急峻な周辺密度勾配と相関することが見出された。セパラトリックス内側の新古典径電場井戸の最小値の推定は、固定されたトロイダル磁場()におけるすべての解析されたL-H遷移に対して一定値を与える。パワー閾値の減少は、全タングステン壁放電におけるより急峻な密度勾配によって説明される。
