摘要 本文对一种新型的工作在二次谐波的三腔回旋速调管进行了理论分析和PIC模拟,该管子有两个十分突出的优点:由于其是工作在二次谐波上,这就大大降低了对轴向磁场的要求,可以避免笨重的螺线管或是超导磁场;其次由于其为三腔的结构,可以明显的提高管子的增益.PIC(ParticleInCell)模拟方法被采用来对该管子从磁控注入枪到微波电路进行了电磁模拟.在我们所采用的参数条件下,工作频率为35GHz,工作模式为TE021的三腔回旋速调管在0.675T的磁场下得到了22.5dB的增益以及23.71%的效率. The theoretical analysis and PIC simulation of a new kind of 35 GHz gyroklystron is presented. This gyroklystron has all stages operate at the second harmonic to avoid the use of cryomagnets or heavy and bulky solenoids, and its three cavity's structure can greatly enhance its gain. PIC method is used to simulate this gyroklystron, the results shows that this gyroklystron can produce an output peak power of 249 kW with 22.5 dB gain and 23.71% maximum efficiency at 35 GHz.
