Abstract :
Presents the complete design of a 34-GHz, four-cavity coaxial gyroklystron experiment. The 500-kV, 300-A beam is produced by a double anode magnetron injection gun (MIGc) with an average perpendicular-to-parallel velocity ratio of 1.5 and a parallel velocity spread of less than 5%. The microwave circuit has a first-harmonic TE011 input cavity that is driven at 17.135 GHz. It has buncher, penultimate, and output cavities that operate In the TE021-mode and are resonant near the second harmonic of the gyrofrequency. A peak power of 55 MW is obtained with a 47-46 gain and 36.5% efficiency. A complete description of the system is presented. We also present scaled circuit designs at 17 GHz and 91 GHz.
