介绍了在电子直线加速器粒子动力学基础上进行聚焦线圈轴向磁场的设计；利用ＬＩＮＥ－ＡＣＣ／ＰＣ程序模拟计算，给出了不同初始发射度情况下满足束流包络要求的各种聚焦磁场数据。对已经加工好的聚焦系统进行了磁场分布测量，并将实际磁场与理论计算进行了比较。上述工作为确定聚焦线圈的设计方案和加速器的出束实验提供了可靠、丰富的数据。
The design of the axial magnetic field of the focusing coil based on the particle dynamics of the electron linear accelerator is introduced. Using the LINE-ACC / PC program simulation calculation, various focusing magnetic fields that meet the requirements of the beam envelope under different initial emissivities are given. data. The magnetic field distribution of the focused system has been measured, and the actual magnetic field has been compared with the theoretical calculation. The above work provides reliable and abundant data for determining the design scheme of the focusing coil and the beam-out experiment of the accelerator.
