Abstract

Introducing FEM-CMFD (Finite Element Method for Calculating Magnetic Field Distribution), a new program designed for calculating the magnetic field distribution for axially symmetric complex magnetic systems, such as magnetic lenses. The program operates by reading user-inputted magnetic system data presented in a two-dimensional graph. Utilizing the finite element method, it calculates the axial magnetic field distribution for various coil excitations accommodating up to approximately 10 000 intersection nodes.

Keywords: Electron magnetic lens, Finite element method, Magnetic field distribution.
