Differential Algebraic Method for Arbitrary High Order Aberration Analysis of Electrostatic Electron Lens Systems 微分代数方法在静电电子透镜任意高阶像差分析中的应用
Specific demonstration of this new technique was shown in the calculation of an electrostatic electron lens, whose axial potential density can be analytically described. 文中还以一个轴上电位分布具有解析表达式的静电电子透镜为例,计算了它的一至三阶复合几何像差色像差系数,并给出了一阶色差分布图形。
