摘要
用表面电荷密度法计算了能量分析器中静电减速透镜的电位分布,用基尔法对电子轨迹进行了模拟,在电子能量为20keV时,得到分析器的能量分辨为1.0eV;讨论了束径、入射角、透镜第三电极孔径对能量分辨的影响;并对个别实验结论作了补充.
The potential distribution in the electrostatic decelerating lens is calculated with chargedensity method. The Gill method is used to simulate the electron orbits. The resolution of the analyzer is 1.0 eV at 20 keV. The influence of the beam diameter, injection angle and the hole diameter of the third electrode to the resolution are discussed. Some additions to the experimental data are given by simulation.
