Efficiency of LH current drive in tokamaks featuring an internal transport barrier

C I de Oliveira, L F Ziebell, P R da S Rosa2005年Plasma Physics and Controlled FusionIF 2.2出版社

In this paper, we study the effects of the occurrence of radial transport of particles in a tokamak on the efficiency of the current drive by lower hybrid (LH) waves, in the presence of an internal transport barrier. The results are obtained by numerical solution of the Fokker–Planck equation which rules the evolution of the electron distribution function. We assume that the radial transport of particles can be due to magnetic or electrostatic fluctuations. In both cases the efficiency of the current drive is shown to increase with the increase of the fluctuations that originate the transport. The dependence of the current drive efficiency on the depth and position of the barrier is also investigated.

本論文では、内部輸送障壁の存在下におけるトカマク内の粒子の径方向輸送が、低混成(LH)波による電流駆動の効率に及ぼす影響について研究する。結果は、電子分布関数の時間発展を支配するフォッカー・プランク方程式の数値解によって得られる。粒子の径方向輸送は、磁気的または静電的揺動に起因すると仮定する。どちらの場合においても、輸送の原因となる揺動の増大に伴い、電流駆動効率が増加することが示される。また、障壁の深さと位置が電流駆動効率に及ぼす影響についても調査する。
