Impurity transport in the collisional regime for large poloidal variations

C.S. Chang, R.D. Hazeltine1980年被引用 30Nuclear FusionIF 3出版社

Impurity transport is studied in a toroidal plasma column with large poloidal variations of the plasma parameters (comparable to the variation of the magnetic field) near the edge. It is found that the highly collisional nature of the edge plasma can lead to such variations of density and electrostatic potential. The impurity transport coefficients are significantly modified by this effect, becoming non-linear in the gradients.

不純物輸送が、周辺部近傍でプラズマパラメータの大きなポロイダル変動(磁場の変動に匹敵する)を持つトロイダルプラズマ柱において研究される。周辺プラズマの高衝突性が、密度と静電ポテンシャルのそのような変動を引き起こし得ることが見出された。不純物輸送係数はこの効果によって有意に修正され、勾配に対して非線形になる。
