Current drive by toroidally bounded whistlers

S.K.P. Tripathi, D. Bora2002年被引用 11Nuclear FusionIF 3出版社

Low-frequency bounded whistlers have been launched in a toroidal system to produce a high-density plasma. These waves generate a completely different wave field pattern in the toroidal plasma cavity as compared to helicon waves in thin cylindrical plasma columns. Based on the excitation of toroidal bounded whistlers, which sustain the discharge, a new approach to the problem of current drive is discussed. 1.0–1.5 kA of plasma current is driven with 1.0 kW of input radiofrequency (RF) power. The same RF source sustains steady-state plasma with 1012 cm−3 peak density and 18 eV electron temperature. Along with studies on the dependence of plasma current on wave and plasma parameters, resonant and nonresonant contributions to the total plasma current are estimated.

低周波有界ホイッスラー波がトロイダル系において発射され、高密度プラズマを生成した。これらの波は、細い円筒形プラズマ中のヘリコン波と比較して、トロイダルプラズマ空洞内に完全に異なる波動場パターンを生成する。放電を維持するトロイダル有界ホイッスラー波の励起に基づき、電流駆動の問題に対する新しいアプローチが検討される。1.0kWの入力高周波(RF)電力により、1.0~1.5kAのプラズマ電流が駆動される。同じRF源は、ピーク密度10¹²cm⁻³、電子温度18eVの定常プラズマを維持する。プラズマ電流の波動パラメータおよびプラズマパラメータへの依存性に関する研究に加えて、全プラズマ電流に対する共鳴的寄与と非共鳴的寄与の評価が行われる。
