Abstract :
Presents a design of a 1-MV, frequency-doubling, four-cavity gyroklystron. The input cavity is driven by a 17.5-GHz driver and operates in the transverse electric (TE)011 mode at the fundamental cyclotron resonance, while the buncher, penultimate, and output cavities operate in the TE021 mode at twice the signal frequency at the second cyclotron harmonic. The device exhibits about 40% efficiency and 40-dB gain at 1-MW power level with a fractional bandwidth exceeding 0.1%. The power-bandwidth product for this device is on the same order as that of Ka-band gyroklystrons without the frequency doubling feature.
