Simulation investigation of X-band magnetically insulated line oscillator

According to theoretical analysis of the slow-wave structure(SWS), the parameters of SWS, the cathode and the anode are chosen. A new type X-band magnetically insulated line oscillator(MILO) has been designed using the advantages of both tapered MILO and loadlimited MILO. Through numerical simulations by a 2.5-D PIC code, the impacts of several structure parameters of MILO on its output power are investigated. High power microwave is generated from the optimized MILO by simulation with the average output power of 2.83 GW, the frequency of 8.2 GHz and the efficiency of 12.9%, when the beam voltage is 510 kV and current is 43 kA．
