Electrostatically trapped electrons in thermal-barrier tandem mirrors

M.E. Rensink, R.H. Cohen, A.A. Mirin, G.P. Tomaschke1984年被引用 4Nuclear FusionIF 3出版社

Electron confinement in the plug regions of thermal-barrier tandem mirrors is examined. Analytical and numerical (Fokker-Planck code) approaches are presented for small-to-intermediate mirror ratios including the effects of passing particles and electron heating. Steady-state trapped-electron densities and mean energies from the theory and code agree to within 20% for mirror ratios 0 ≤ R ≤ 2.2 with and without passing particles. Electron heating and detrapping by strong RF diffusion is demonstrated computationally for parameters expected in the TMX-U experiment.

熱障壁タンデムミラーのプラグ領域における電子閉じ込めを検討する。小から中程度のミラー比に対する解析的アプローチと数値的(フォッカー・プランクコード)アプローチを提示し、通過粒子と電子加熱の影響を含める。理論とコードによる定常状態の閉じ込め電子密度と平均エネルギーは、通過粒子の有無にかかわらず、ミラー比0≦R≦2.2において20%以内で一致する。TMX-U実験で予想されるパラメータに対する強力なRF拡散による電子加熱と脱閉じ込めを計算機的に実証する。
