摘要: 基于高频信号相位测量原理，提出了S波段相对论速调管放大器相位测量的方法。对S波段800 kW速调管放大器进行了验证实验，并测试了S波段相对论速调管放大器的相位。实验结果表明：速调管输入和输出微波相位差随束压升高而减小，随束流升高而增大，微波相位差不随注入微波功率大小和磁场变化而变化。Abstract: Based on the phase measurement principle of RF signals, the method of S-band relativistic klystron amplifier(RKA) phase measurement was put forward. The experiment of the 800 kW S-band RKA was performed and the phase measurement of S-band RKA was tested. The experimental results show that the phase difference between the input microwave and output microwave declined due to the increase of the beam voltage and decrease of the beam current, the phase difference did not vary with the amplitude of the input microwave and magnetic field．
