Current drive by high parallel phase velocity waves in the presence of a DC electric field

K Borrass, A Nocentini1984年Plasma Physics and Controlled FusionIF 2.2出版社

The one-dimensional Fisch theory of plasma heating and current drive by high parallel phase velocity waves is generalized to include the effect of a parallel electric field. It is shown that in the presence of an electric field parallel (antiparallel) to the RF current, the power absorption, the RF current and the current drive efficiency increase (decrease). Electric field effects can be strong during current ramp-up or when recharging the transformer in Tokamaks. The results are given in analytical form, allowing direct application to transport modelling.

一次元のフィッシュ理論による高平行位相速度波を用いたプラズマ加熱と電流駆動を、平行電場の効果を含むように一般化する。RF電流に平行(反平行)な電場が存在する場合、電力吸収、RF電流、および電流駆動効率が増加(減少)することが示される。電場の効果は、トカマクにおける電流立ち上げ中や変圧器の再充電時に強くなり得る。結果は解析的な形式で与えられ、輸送モデリングへの直接的な適用が可能である。
