The magnetic field surrounding a coil is used to focus electron beams. The particle trajectories in the magnetic lens are computed using the Particle Tracing Module. If you are interested in magnetic field simulation, or modeling the motion of large quantities of discrete particles moving under the influence of forces generated by a background field, this video is for you. The Magnetic Lens model presented in this video can be downloaded from our Model Gallery.
This is Chapter 1 of 2. Watch Chapter 2, Simulating a Magnetic Lens: Postprocessing.
本例通过线圈周围的磁场使电子束聚焦,使用“粒子追踪模块”计算磁透镜中的粒子轨迹。如果您对磁场仿真感兴趣,或者希望模拟大量离散粒子在背景场产生的力的影响下的运动情况,建议您观看本视频。欢迎访问“案例下载”页面,下载本视频中展示的磁透镜模型。
这是本系列视频的第 1 章(共 2 章)。欢迎观看第 2 章:模拟磁透镜:后处理。
