静电浸没物镜在宽束成象器件中有着广泛的应用,而这些器件制作的成本一般来说又是比较高的。在电子计算机高度发展的今天,事先对该器件电子光学系统的精确设计是非常必要的。同时,在器件制作之前,对其设计质量作一合理的评价也是极为需要的。为此,我们编制了J—21机静电电子光学系统设计计算通用程序。其中包括电位计算、轨迹计算、电位 Electrostatic immersion objective lenses are widely used in wide beam imaging devices, and the cost of making these devices is generally relatively high. In today’s highly developed electronic computer, the accurate design of the electronic optical system of the device is necessary beforehand. At the same time, before the device is produced, it is extremely necessary to make a reasonable evaluation of its design quality. To this end, we have compiled a general program for the design and calculation of J-21 electrostatic optics systems. Including the potential calculation, trajectory calculation, potential
