Abstract :
In our experimental study a periodic medium loaded structure is used as the high-frequency structure of the Ka-band Gyro-TWT. The experimental measurement is carried out when the accelerating voltage is 66kV and the electron beam current is 13A. A peak output power of 293 kW, a maximum gain of 56 dB, an efficiency of 34.2% and a 3dB bandwidth of 2.1GHz are measured.
