摘要

磁透镜(磁场透镜)使用磁场而不是等势平面。本文提出了聚焦磁透镜的设计模型。其主要目的是揭示这种透镜消除像差的可能性，并确定其在电子显微镜和电子束熔化系统设计中的潜力程度。这项工作是通过COMSOL多物理场仿真软件完成的。通过逐步改变孔径半径从1到4，对磁透镜进行了测试，以确定其在电子显微镜下包含的可能性。该数学模型是研究电子光学的一个很好的工具。

Performance and Analysis of a Designed Magnetic Lens for Microscopic Applications

The magnetic lens (magnetic field lens) uses a magnetic field rather than an equipotential plane. This work presents a modelling of the design of a focused magnetic lens. Its main purpose is to reveal the possibility of this lens to eliminate aberrations and to determine the extent of its potential to be included in the design of electron microscopes and electron beam melting systems. This work was accomplished by using COMSOL Multiphysics simulation software. The magnetic lens was tested to determine the possibility of its inclusion in electron microscopes by changing the bore radius from 1 to 4 step by step. The proposed mathematical model was proven as an excellent tool in electron optics.
