A Compact C-Band Magnetically Insulated Line Oscillator

The magnetically insulated line oscillator (MILO) is a high power microwave (HPM) pulsed device, potentially of gigawatt power, that combines the technologies of magnetically insulated electron flow with a slow wave structure (SWS). This combination makes the tube a device capable of operating over a wide voltage range. Our concern is to design a compact experimental setup. Using the theoretical and experimental results as guides, a novel RF choke and a beam dump disk have been introduced into the MILO. In experiments, high power microwave of the TM ₀₁ mode is generated from the device with a frequency range of 3.70-3.72 GHz and a power level of above 500 MW, when the diode voltage is 400-430 kV and the beam current is 30-33 kA. The experimental results are in agreement with the computation values
