“…Additionally, the ladder cathode is adopted to replace the traditional uniform cathode, which is beneficial to the improvement of the conversion efficiency. [30][31][32] The edges of all the vanes used to constitute the SWS cavities are rounded with a radius of 1 mm to reduce the RF field of the SWS surface, which is conducible to improving the power capacity and minimizing the risk of rf breakdown. In order to enhance the power capacity, the improved Ku-band MILO adopts overmoded SWS.…”

In order to enhance the power capacity, an improved Ku-band magnetically insulated transmission line oscillator (MILO) with overmoded slow-wave-structure (SWS) is proposed and investigated numerically and experimentally. The analysis of the dispersion relationship and the resonant curve of the cold test indicate that the device can operate at the near π mode of the TM01 mode, which is useful for mode selection and control. In the particle simulation, the improved Ku-band MILO generates a microwave with a power of 1.5 GW and a frequency of 12.3 GHz under an input voltage of 480 kV and input current of 42 kA. Finally, experimental investigation of the improved Ku-band MILO is carried out. A high-power microwave (HPM) with an average power of 800 MW, a frequency of 12.35 GHz, and pulse width of 35 ns is generated under a diode voltage of 500 kV and beam current of 43 kA. The consistency between the experimental and simulated far-field radiation pattern confirms that the operating mode of the improved Ku-band MILO is well controlled in π mode of the TM01 mode.
