摘要：文章选取杯状纵磁灭弧室触头为试验对象,对同一结构、不同直径、不同杯壁厚度、不同触头开槽偏移距离以及槽指与水平角度对纵向磁场的影响进行了正交设计试验。使用有限元仿真软件得出结果,得到其触头中心4.5mm处的纵向磁感应强度。并通过方差分析,得到其显著与非显著因素,再对其显著因素进行回归分析,得到显著因素与中心纵向磁场感应强度的回归方程。通过多组试验数据,验证了其回归方程的准确性,得到了原触头的最优组合。

摘要：One of the most important components of a linac is buncher. Throughout most of the buncher, the electrons are well forward of the crest and have velocities considerably less than light velocity, thus they are in a region of radial defocusing and a considerable fraction of the beam will be lost unless defocusing action is counteracted by some other applied forces. The simplest way to do this is to set up a longitudinal magnetic field which interacts with the radial motion of the electrons and causes them to follow helical orbits through the space occupied by the field. In this paper, five solenoids were designed to provide necessary magnetic field inside the buncher. Magnetic field was analytically calculated and compared with simulation results of Computer Simulation Technology (CST). Because of resistance in wires, some amount of energy appears in form of heat, so heat power was calculated analytically and cooling system was designed for these solenoids by Analysis System (ANSYS).
