FEL-THz电子枪控制系统的设计与实现

摘要

介绍了 FEL-THz装置中电子枪控制系统的设计与实现过程。利用 Microsoft公司发布的 Visual C++6.0进行了控制系统软件的开发和设计。实验结果显示，该软件操作简捷，具有良好的人机操作界面，程序实时响应速度快，运行稳定，为电子枪高压老炼以及系统测评提供支持。%There are rigorous requirements on the characteristic of electron beams in Free Electron Laser(FEL) operation, such as high brightness and high average current. High voltage DC electron gun with photo-cathodes has become the first choice for generating the beams. A high voltage DC electron gun is designed to work stably at 350 kV. The software of the control system is developed in VC++ 6.0 for DC gun. The experimental results indicate that the control software can be operated easily with friendly interface and rapid response speed. It can provide support for the high-voltage aging of electron gun and system evaluation due to its good reliability and stability.
