Abstract

A four cavity W-band gyroklystron amplifier experiment is currently underway at the Naval Research Laboratory. The gyroklystron has produced 67 kW peak output power and 28% efficiency in the TE₀₁₁ mode with a 55 kV, 4.3 A annular electron beam. The full width half maximum (FWHM) bandwidth is greater than 460 MHz. Small signal and saturated gains of 36 dB and 29 dB, respectively, have been observed. The amplifier is zero drive stable and the limiting oscillation is the TE₀₁₁ operating mode in the output cavity. Experimental results are in good agreement with theoretical predictions
