Numerical study on microwave generation characteristics of bifrequency MILO

By way of numerical analysis, microwave generation characteristics of bifrequency magnetically insulated transmission line oscillators (BFMILOs) with azimuthal partition proportions of 1∶1, 1∶2, 1∶3, 2∶1 and 3∶1 are investigated. The microwave field distributions, the phasespace of electrons, the output microwave power and microwave frequencies as the function of angle on the hotcavity condition are obtained. In order to make comparison, two conventional MILO with two kinds of cavitydepth corresponding to the BFMILO are simulated and their simulation results are presented. The numerical study further shows the rule that the interaction between electron beam and microwave in BFMILO is separate in different particular partition, and it makes clear the mechanism of high power microwa
