摘要
为了提高返波管的工作效率,本文模拟设计了一个X波段非均匀周期慢波结构的相对论返波管。模拟结果表明:在电压为719k V,电流为10.2k A,磁场为3.0T条件下,微波输出功率为2.81GW,工作频率为9.04GHz,效率为38.3%,输出模式为TM01模。模拟结果表明,采用非均匀周期慢波结构有效地提高了器件的工作效率。论文同时模拟研究了电子束电压对器件输出功率、效率、工作频率的影响。
The operation efficiency of the even-period relativistic backward wave oscillator(RBWO) with slow-wave structure was low. In order to obtain a higher efficiency, we design an X-band uneven-period RBWO. The simulation demonstrates that when the voltage is 719 k V, the current is 10.2k A and the magnetic field strength is 3.0T, a microwave with power of 2.81 GW is generated, with an conversion efficiency of 38.3%. The frequency of the output microwave is 9.04 GHz, and the output mode appears as TM01. As shown in the results, the uneven-period slow wave structure can promote the operation efficiency of the devices. Moreover, we analyze how the electron-beam voltage influences the output power, efficiency and the operation frequency.
