Experimental research on Ku-Band MILO

An improved Ku-band magnetically insulated transmission line oscillator is proposed and investigated experimentally. In the particle-in-cell simulation, the Ku-band MILO generates microwave with power of 1.62GW and frequency of 13GHz at the input voltage of 474kV. The device is fabricated based on the simulation results and an experiment system is designed. In the preliminary experiments, output microwave with frequency of 13.02GHz, power of 150MW, and pulse width of 17ns is generated, under the diode voltage of 450kV. Analysis on the experiment results shows that plasma produced due to the large current hitting to the outside of the collection tank is the essential cause for the low amplitude of the microwave power and short pulse width.
