| Abstract: | The design of a W-band four-cavity gyroklystron amplifier is presented. The device operates in the fundamental harmonic TE01 circular electric mode. The 70-kV, 6-A beam is produced by a double anode magnetron injection gun (MIG) with an average perpendicular-to-parallel velocity ratio of 1.5 and a parallel velocity spread of less than 4%. Particle-in-cell (PIC) simulations have been performed to predict general RF performance for various parameters. The simulated results show that the designed gyroklystron amplifier can produce about 35dB gain, 800MHz bandwidth and 100kW peak output power corresponding to power conversion efficiency of 23.8% for a beam with 4% axial velocity spread. |
