| 摘 要： | 对电子回旋共振加热（ECRH）产生晃荡电子形成串级磁镜热垒的物理过程进行了Fokker-Planck动力学计算，计算表明：（1）在一定条件下，晃荡电子等离子体位形形成，其密度比neh（Zr）/neh（O）=2.15，且形成了ΔΦ=16.5V的静电势阱；（2）静电势阱的建立分为迅速建立、逐渐减少和稳定平衡三个阶段，这是ECRH、碰撞散射和俘获离子共同作用的结果关键词：

| Abstract: | The physical process of using ECRH to produce sloshing electrons and to form tandem mirror thermal barrier is calculated by means of Fokker Planck kinetic equation.The results show that (1)under certain conditions,the sloshing electron plasma configuration has been formed,the density ratios of which neh(Zr)/neh(0)=2.15 and the potential dip ΔФ=16.5V have also been formed;(2)there are three stages consisting of rapid establishment,gradual decrease and stable equilibrium in the establishment of potiential dip,which result from the coaction of ECRH,collision scattering and trapped ions. |
