Electron dynamics and the enhancement of Q in mirror-magnetic wells

L.S. Hall1977年被引用 32Nuclear FusionIF 3出版社

It is shown that reconsideration of the electron dynamics leads to significant corrections in computing the classical equilibrium of mirror confinement systems. The need to revise earlier models is shown by comparison with experiment. The effect of an external plasma upon energy loss is examined, and an analysis of the problems of secondary emission at end walls is made. New computations of the quality parameter Q and of nτ are made from Fokker-Planck equations modified to more realistically account for the electron dynamics. Curves are plotted enabling optimal values of Q and nτ to be determined through control of the electron temperature (i.e. electron energy losses) and through control of the ambipolar potential.

電子動力学の再考察が、ミラー閉じ込め系の古典的計算における有意な補正をもたらすことが示される。初期のモデルを修正する必要性は、実験との比較によって示される。外部プラズマがエネルギー損失に及ぼす影響が検討され、端壁における二次電子放出の問題の解析が行われる。品質パラメータQおよびnτの新たな計算は、電子動力学をより現実的に考慮するよう修正されたフォッカー=プランク方程式から行われる。電子温度(すなわち電子エネルギー損失)の制御および両極性電位の制御を通じて、Qおよびnτの最適値を決定することを可能にする曲線がプロットされる。
