大功率速调管自激振荡实验研究

Experiment Study on Self-amplified High-Power Klystron

利用北京自由电子激光装置中的微波系统 ,进行了大功率速调管自激振荡的实验研究 .通过调节速调管在振荡模式工作时的反馈回路参数 ,对速调管自激振荡输出功率、频率和频率稳定性、建立时间等性能进行了测量 ,实验结果说明大功率速调管振荡工作模式可以满足作为电子直线加速器微波功率源的要求 .

The experiment study on self amplified high power klystron is carried out in the microwave system of BFEL. The performance of the self amplified klystron including output power, frequency, frequency stability, buildup time etc. is measured by modalating its feedback parameters. The experiment results show that the self amplified klystron can be used as one of the microwave sources in electron LINAC for the industrial application.
