Abstract

Abstract

The magnetically insulated transmission line oscillator(MILO) is a crossed-field microwave tube that is closely related to the linear magnetron. The theoretical model of the self-magnetically insulated transmission line oscillator is established, and the formula of the insulating current is given. Then the formula of the maximum spoke current is given, and the maximum efficiency of the load-limited MILO is analyzed. A new type of gap-current MILO is presented. The PIC simulation shows that the steady-state value of average output power of this MILO is around 6.1 GW with an effciency of about 18.64% when the AK-gap voltage is 590 kV, the current is 55.47 kA, and the corresponding frequency is 1.24 GHz. The efficiency of the gap-current MILO is about 6% higher than that of the load-limited M
