Computational study on propagation and two-species-ion-plasma heating due to the ion-Bernstein wave

H Okada, H Abe, R Itatani, M Ono1987年Plasma Physics and Controlled FusionIF 2.2出版社

The propagation of the ion-Bernstein wave and resulting heating at 5 Omega D resonance are investigated in a two-component ion plasma (D-H) by means of particle simulation. The propagation of the ion-Bernstein wave observed in the simulation can be characterized by the linear theory. The wave energy is deposited locally around the 5 Omega D resonance region located in the center of the system due to the direct energy absorption into D and H through the 5 Omega D resonance and 5/2 Omega H subharmonic resonance. The bulk of the velocity distribution of H is heated. For the deuterium species, generation of high energy tail ions is observed as well as the heating of the bulk of the velocity distribution.

イオン・バーンスタイン波の伝播と、5ΩD共鳴における加熱を、粒子シミュレーションにより2成分イオンプラズマ(D-H)中で調べた。シミュレーションで観測されたイオン・バーンスタイン波の伝播は、線形理論によって特徴づけられる。波動エネルギーは、系の中心に位置する5ΩD共鳴領域の近傍に局在的に堆積され、これは5ΩD共鳴および5/2ΩH副共鳴を通じたDおよびHへの直接的なエネルギー吸収によるものである。Hの速度分布のバルクが加熱される。重水素種については、速度分布のバルクの加熱に加えて、高エネルギーテイルイオンの生成が観測される。
