Abstract

Summary form only given. Experimental research on L-band magnetically insulated transmission line oscillator (MILO) is carried out for the generation of the microwave of ~GW power. This MILO is composed of 6-uniform cavities and single coupling cavity and two choke cavities. The measured output power of 2.8 GW shows a reasonable agreement with the simulated one of 2.75 GW. In this experiment, 500 kV-36 kA pulsed electron beam with the pulse duration of 130nsec is used. The pulsewidth of the microwave is limited to 70ns mainly due to a mode competition between axial modes. The mode change during the pulse is measured by RF B-dot probes at each cavity. Dynamic of mode competition is studied with time-frequency analysis.
