Recent progress in lower hybrid current drive theory and experiments

E Barbato1998年Plasma Physics and Controlled FusionIF 2.2出版社

In this paper lower hybrid current drive (LHCD) experimental milestones paving the way for future experiments are briefly summarized. The current drive efficiency scaling with the electron temperature is discussed. The role of wave propagation in determining the power deposition profile is stressed and methods are discussed to control the current density profile. Modelling of negative central shear configurations, experimentally obtained by LHCD, are reported. A good agreement is found between the modelling results and the experimental findings, thus showing that a good degree of understanding has been achieved in LHCD theory.

本論文では、将来の実験への道を開く低域混成波電流駆動(LHCD)の実験的マイルストーンについて簡潔に概説する。電子温度に伴う電流駆動効率のスケーリングについて議論する。パワー堆積分布の決定における波動伝播の役割を強調し、電流密度分布を制御する手法について考察する。LHCDによって実験的に得られた負中心磁気シア配位のモデリングについて報告する。モデリング結果と実験結果の間に良好な一致が見られ、これによりLHCD理論において高度な理解が達成されていることが示される。
