摘要 为提高行波管的增益和输出波形的稳定性,开展了带高频切断X波段大功率耦合腔行波管的研究工作。以点频7.2 GHz为例,对X波段耦合腔行波管的大信号注波互作用过程进行了3维粒子模拟,该行波管包含一处高频切断及两处微波集中衰减器。数值模拟结果表明:行波管腔数为40、电子束电压为17 kV、电流为0.8 A时,可获得2.0 kW的微波输出功率,增益达23 dB,电子效率达14.7%。 To improve the gain and stability of output microwave,an X-band high power coupled cavity traveling wave tube (CCTWT) with one RF sever and two RF lumped attenuators is studied. As an example of dot frequency microwave input, the large signal beam-wave interaction at 7.2 GHz of this X-band CCTWT is simulated using 3D PIC code. The simulated results show that this tube can produce an output power of 2.0 kW,an electron efficiency of 14. 7% and a gain of 23 dB with a cavity number of 40,a beam voltage of 17 kV and a beam current of 0.8 A.
