Abstract
Electron optics theory serves as the foundation for designing electron optical systems and optimizing high-order aberrations. A key challenge in electron optical design lies in the calculation and optimization of lens aberrations. The primary goal of this research is to develop an aberration calculation program for electron lenses using the differential algebraic method. This program aims to evaluate the linear focusing parameters and high-order aberration coefficients (up to fifth-order) of electromagnetic lenses, which are critical for improving the resolution and performance of electron microscopy systems. Furthermore, a more interactive and comprehensive GUI interface has been developed, centered around this aberration calculation program. It supports optical parameter computation and particle trajectory tracking for electrostatic, magnetic, and electromagnetic lenses. By employing GPU-accelerated computing, high-efficiency visualization of large-scale particle trajectories has been achieved. This program serves as a powerful analytical tool for the hardware design of electron optical systems.
