| 摘 要： | 对长周期永磁聚焦系统中电子注的脉动情况进行了系统的研究。在增大磁系统周期的时候,从理论上讨论了高次谐波,磁场参量和空间电荷参量对电子注脉动的影响,最后利用计算机仿真软件OPERA对电子注在长周期磁聚焦系统中的运动进行了模拟。结果表明,理论推导的结果与计算机模拟值相符,可以利用这种方法进行长周期聚焦系统的模拟和设计。

| Abstract: | The magnetic circuits of a long period focusing system are systematically studied on this paper.The electronic beam shift which is affected by harmonic waves,magnetic parameter and space electronic parameter has been discussed by both theoretical calculation and computer simulations.The E-beam trajectories in LPPM focusing system have been simulated using the computer software OPERA with satisfactory agreement.The results can meet the demand of engineering simulation and design. |
