A semi-analytical method to evaluate the dielectric response of a tokamak plasma accounting for drift orbit effects

Dirk Van Eester2005年Plasma Physics and Controlled FusionIF 2.2出版社

A semi-analytical method is proposed to evaluate the dielectric response of a plasma to electromagnetic waves in the ion cyclotron domain of frequencies in a D-shaped but axisymmetric toroidal geometry. The actual drift orbit of the particles is accounted for. The method hinges on subdividing the orbit into elementary segments in which the integrations can be performed analytically or by tabulation, and it relies on the local book-keeping of the relation between the toroidal angular momentum and the poloidal flux function. Depending on which variables are chosen, the method allows computation of elementary building blocks for either the wave or the Fokker–Planck equation, but the accent is mainly on the latter. Two types of tangent resonance are distinguished.

イオンサイクロトロン周波数領域における電磁波に対するプラズマの誘電応答を評価するための半解析的手法を、D字型であるが軸対称なトロイダル幾何学において提案する。粒子の実際のドリフト軌道が考慮される。本手法は、軌道を基本セグメントに分割し、そのセグメント内で積分を解析的または表計算によって実行できるようにすることに基づいており、トロイダル角運動量とポロイダル磁束関数の間の関係の局所的な評価に依存している。選択する変数に応じて、本手法は波動またはフォッカー=プランク方程式の基本構成要素の計算を可能にするが、主に後者に焦点が当てられる。2種類の接線共鳴が区別される。
