Estimation of the Electronic Efficiency of a Gyroklystron Amplifier

In the present paper, a generalized self-consistent single mode linear analysis of gyroklystron has been presented. The analysis has been used to estimate and optimize the electronic efficiency of the gyroklystron device. The efficiency contours, necessary for the preliminary design of a gyroklystron, have been drawn by solving the coupled equations using Runga-Kutta method for the various device parameters. Using these efficiency contours, the electronic efficiency of an experimentally reported Ka band gyroklystron operating at the fundamental harmonic mode has been estimated. The results obtained from the present analysis have been found in match with the reported experimental values within 10%. The present analysis is generalized in nature and would be useful for the initial design of the gyroklystron amplifers of any desired frequency and power.
