Abstract

The continued development of linear accelerators at higher frequencies poses several technological challenges. One such challenge is the requirement for high-frequency amplifiers to drive linearization systems. Presented in this article is the design of a 48 GHz gyroklystron amplifier appropriate for application in a harmonic linearizer for a 6 GHz or 12 GHz drive frequency. The beam used in the gyroklystron is provided by a magnetron injection gun (MIG), which has been designed using genetic optimization. The gyroklystron interaction circuit was designed with the aid of a Particle-in-Cell (PIC) simulation study which predicted 2 MW of output power at 48 GHz with a gain of 35 dB and an efficiency of 38%. This article summarizes the preceding work on the interaction circuit and MIG with additional phase stability analysis as well as presenting the design and analysis of vacuum windows, an input coupler, and the collector.
