Abstract
The experimental demonstration of a four cavity W-band (93 GHz) gyrokl ystron amplifier is reported. The gyroklystron has produced 67 kW peak output power and 28% efficiency in the TE011 mode using a 55 kV, 4.3 A electron beam. The full width at half maximum instantaneous bandwidt h is greater than 460 MHz, a significant increase over the bandwidth d emonstrated in previous W-band gyroklystron amplifier experiments. The amplifier is unconditionally stable at this operating point. Experime ntal results are in good agreement with theoretical predictions.
