摘　　要：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 paper introduces a kind of design of axial magnetic field of focusing coil based on the so-lutions of simultaneous equations of particle dynamics in an electron linac. For various initial emit-tance the data of magnetic field which give satisfied beam envelopes are worked out by LINE-ACC/PC program.The actual magnetic field distribution of the focusing system is measured andthe data are compared with theoretical results. All provide a reliable reference for the design of fo-cusing coil and beam test.
