Abstract:

This interim report describes the measured performance of a three cavity Gyroklystron amplifier designed to operate at X-band with the signal frequency near the second harmonic of the Cyclotron frequency. Efficiency and gain were measured as a function of various operating parameters. Performance of the experimental device was significantly limited by the need to avoid spurious oscillations. The maximum gain was 10 dB and the maximum efficiency was 8 percent. Noise figure and spectrum measurements yielded values similar to high power linear beam tubes. Design considerations for converting the experimental Gyroklystron to a Gyro-TWT are discussed. A Gyro-TWT using the TE11 cylindrical mode with operation at the fundamental Cyclotron frequency was found to be compatible with existing hardware. Considerations for a second experiment using the TE01 cylindrical mode and the second Cyclotron harmonic are also discussed.
