Effect of high order magnetic field harmonics on trapped particle confinement in torsatrons and heliotrons

M.S. Smirnova1996年被引用 6Nuclear FusionIF 3出版社

Charged particle confinement in torsatrons and heliotrons is investigated with account taken of distant, high order magnetic field harmonics. Analytical estimations of the high order harmonics effect on confinement of both the passing and the trapped helical banana trajectories are obtained using bounce averaged equations of particle motion. These estimations are compared with the results of numerical integration of the guiding centre equations of particle motion in magnetic co-ordinates for heliotron/torsatron configurations of pre-reactor and reactor size, such as the Large Helical Device (LHD) and the Force-Free Helical Reactor (FFHR)

トーサトロンおよびヘリオトロンにおける荷電粒子閉じ込めを、遠方の高次磁場高調波を考慮して調べた。高次高調波が通過軌道および捕捉ヘリカルバナナ軌道の両方の閉じ込めに及ぼす影響の解析的評価は、粒子運動のバウンス平均方程式を用いて得られた。これらの評価は、大型ヘリカル装置(LHD)やフォースフリーヘリカルリアクター(FFHR)のようなプレリアクター規模および炉規模のヘリオトロン/トーサトロン配位について、磁気座標における粒子運動の案内中心方程式の数値積分の結果と比較された。
