Transport analysis of lower hybrid current drive plasmas in ASDEX

A transport code has been developed which comprises lower hybrid (LH) wave propagation, absorption, plasma heating, current drive, MHD induced transport and anomalous electron heat conductivity. This code was applied to a set of ASDEX discharges covering a wide range of LH experiments. Suppression of sawteeth and m=1 oscillations with subsequent strong peaking of the electron temperature profile and the dependence of the confinement time on power and density are described self-consistently in the simulation. In MHD stable LHCD plasmas with high central electron temperatures and peaked Te(r) profiles, the electrons heat conductivity in the central plasma region approaches the magnitude of neoclassical values

低ハイブリッド(LH)波の伝播、吸収、プラズマ加熱、電流駆動、MHD誘起輸送、および異常電子熱伝導を含む輸送コードが開発された。このコードは、広範囲のLH実験をカバーする一連のASDEX放電に適用された。鋸歯状振動およびm=1振動の抑制と、それに続く電子温度分布の強いピーキング、ならびに閉じ込め時間のパワーと密度への依存性が、シミュレーションにおいて自己無撞着に記述されている。高い中心電子温度とピーキングしたTe(r)分布を有するMHD安定なLHCDプラズマにおいて、中心プラズマ領域での電子熱伝導は新古典値の大きさに近づく。
