以中国科学院近代物理研究所正在研制的轴对称磁透镜为例,设计了两种结构的轴对称磁透镜:带屏蔽铁壳的螺线管透镜和极靴形状为锥形的Glaser透镜.带屏蔽铁壳的螺线管透镜产生的轴对称磁场比较均匀,而极靴形状为锥形的Glaser透镜产生的轴对称磁场比较集中.分别采用了两种物理模型计算磁场,同时应用有限元分析软件ANSYS进行数值模拟,最后从物理和工程角度对这两种透镜作了全面比较,得出带屏蔽铁壳的螺线管透镜结构更符合设计要求.

The axially symmetric magnetic lens in the Institute of Modern Physics of the Chinese Academy of Sciences is taken as an example in this paper, and two axially symmetric magnetic lenses are designed: one is the solenoid with iron yokes and the other is the Glaser magnet with tapered poles. The axially symmetric magnetic field produced by the solenoid with iron yokes is more even, and the axially symmetric magnetic field produced by the Glaser magnet with tapered poles is more concentrative. Two physical models are applied for approximate calculation of magnetic field, and the ANSYS finite element method is used to simulate the magnetic field at the same time. Comparison is made between the two different lenses in physics and engineering aspects, and the result is that the solenoid with iron yokes meets the design requirement better.
