Abstract :
We have tested 3 and 4-cavity frequency-doubling gyroklystrons that have produced 25 MW of power at 17.14 GHz. We have encountered two problems that have prevented enhanced performance: an input cavity instability and non-uniform emission. In this paper we present the design modifications which we hope will enable operation at the design power level of 80 MW.
