New type MILO using load current to produce microwave

摘要: 为了进一步提高MILO产生微波的功率和效率，提出了其负载电流能量全部利用来产生微波的新思想。设计并运用二维全电磁PIC方法模拟了基于此思想的新型MILO，它是传统MILO与VCO的有机结合(简称MVO)。模拟结果表明MVO中MILO部分与作为MILO负载的VCO部分各自工作正常，VCO部分产生微波的主频受MILO部分产生微波的牵引。在输入25GW电功率（工作电压约500kV）下，与相应传统MILO相比，MVO的微波平均输出功率提高了500MW，效率从6%提高到了8%。Abstract: In order to essentially improve microwave output power and efficiency, a new idea about magnetically insulated transmission line oscillator (MILO) is brought forward, which use most of the load current to produce microwave. A new type of MILO that comprises traditional MILO and VCO, called MVO, is designed and simulated by 2D PIC method. The results show that both parts of MVO work well and the main frequency accords with slowwave structure (SWS), and that MVO yields an output power of 500MW higher than traditional MILO in the case of 25GW(at 500kV) inputpower with the efficiency enhanced from 6% to 8%.
