The quasioptical gyrotron at the Naval Research Laboratory will be converted to an 85 GHz gyroklystron by the addition of a prebunching resonator and an external source. The experiment will investigate longitudinal-mode selection, efficiency enhancement, and phaselocking in a quasioptical resonator. This paper presents results of the design calculations.
