激光同位素分离中离子取出过程的研究

INVESTIGATION OF JON EXTRACTION IN LASER ISOTOPE SEPARATION

本文研究了激光同位素中离子取出的动力学过程。用Poission方程计算了等离子体内的电位分布。用一维流体模型计算分析了收集腔内离子数随时间的演化过程。通过对交流和直流收集方式的比较。得到了交流场的收集效率明显高于直流场这一结论。

The dynamic process for ion extraction in laser isotope separation is studied. Using Poission equation,we calcula the distribution of electric potential in a plasma.Using one-dimension-fluid model, we calculate the evolution of ion and elctron densities in collecting cavity. Comparing the extraction efficiency using the way of alternating current field with the one using the way of direct current field, we have found that the efficiency of A.C.way is higher than the one of D.C.way.
