| 摘 要： | W 波段回旋速调管具有高增益和高输出功率的特点，在军用雷达方面有广泛的应用。本方利用电磁粒子模拟
软件CHIPIC 设计了一个W 波段五腔回旋速调管，优化了互作用电路的结构和工作参数，分析了电子注与场的换能
过程以及工作频率对输出效率和增益的影响。该管的工作模式为TE01 模，当工作电压为70kV、电流为6A、频率为
93.8GHz 时获得了167.3kW 的最大输出功率和39.8%的工作效率。当工作频率为93.65GHz 时取得了50dB 的增益和
400MHz 的带宽。该模拟结果对回旋速调管在雷达方面的应用提供了理论依据。

| Abstract: | gyroklystrons operated at W-band are widely used in radars because of their ability of high power and
high gain. A W-band gyroklystron with five cavities was designed, the structure and the operation parameters of the
interaction circuit was optimized. The process of energy transform and the influence of the operation frequency on the gain
and efficiency was also analyzed. The operation mode of the gyroklystron was TE01, its operation voltage and current was
70kV and 6A respectively. The maximal output power 167.3kW was achieved at the frequency of 93.8GHz with the
efficiency of 39.8%. The maximal gain 50dB was achieved when the working frequency was 93.65GHz with the
bandwidth of 400MHz. The results are very useful for the application of gyroklystrons on radars. |
