Experimental design of a compact L-band magnetically insulated transmission line oscillator

A compact L-band magnetically insulated transmission line oscillator (MILO) is configured and fabricated．When the input voltage is 515～538kV, and the diode current is 58～61kA, high power microwaves of the TM01 mode are generated from the device with the frequency of 176～178GHz，output power of 22～25GW， and the power conversion efficiency of 73%~79%in experiments. The experimental results agree well with that of simulation.
