摘要：
The distributed wall loss is a good approach for the suppression of spurious oscillations in gyrotron traveling-wave tube (gyro-TWT). The periodic lossy dielectric loading in the interaction region of gyro-TWT can effectively suppress the spurious oscillations. We designed and employed a periodic lossy-material-loaded circuit in our experimental study of TE01 Ka-band gyro-TWT. The output characteristics were greatly improved. A peak output power of 290 kW was measured with 56-dB maximum gain, 34.2% efficiency, and 2.1-GHz 3-dB bandwidth when the accelerating voltage was 66 kV and beam current was 13 A.
