IAE(原子研究所)建立了一台3 db定向耦合S波段高功率行波谐振环路。该装置由一个脉冲速调管馈送功率,环路内处于10~(-7)mmHg高真空。在脉宽为2.1μs,重复频率为50次/秒,环内达到的最高脉冲功率为25 MW,此时环路输入功率为5.2 MW。在重复频率为240次/秒时,环内达到的最高平均功率为10 kW。环路功率“倍增”系数为4.8,环路衰减为0.37 db,环路电压驻波比和环路输入臂电在驻波比均小于1.2。该装置已用于高功率微波元件的耐功率试验。
IAE (Institute of Atomic Energy) has established a 3 db directional-coupled S-band high-power traveling-wave resonator loop. The unit feeds power from a pulsating klystron, with a high vacuum of 10 -7 mmHg in the loop. The pulse width is 2.1μs, the repetition frequency is 50 times / second, the maximum pulse power reached in the ring is 25 MW, and the loop input power is 5.2 MW at this moment. At a repetition rate of 240 beats / second, the maximum average power reached in the ring is 10 kW. The “doubling” coefficient of loop power is 4.8 and the loop attenuation is 0.37 db. The VSWR of the loop and the input power of the loop are both less than 1.2 at VSWR. The device has been used for high-power microwave component of the power test.
