高亮度注入器磁聚焦系统,是保证强流电子束在注入器中(包括电子枪、分频腔、聚束器、漂移段)具有良好的聚束性能和高效率传输的重要主成部分。它采用螺旋管线圈的轴向磁场,实现对电子束的聚焦作用。聚焦线圈的布置如图1所示。 High-brightness injector magnetic focusing system is an important main part to ensure that the high-current electron beam has good beam-forming performance and high-efficiency transmission in the injector including the electron gun, frequency division cavity, beam condenser and drift section. It uses the helical coil axial magnetic field, to achieve the focus of the electron beam. Focusing coil layout shown in Figure 1.
