Abstract

In this paper, a gyroklystorn operating at 36 GHz was designed to drive a harmonic linearizer for the CompactLight Xray Free electron laser. Linear theory, non-linear theory and Particle-In-Cell simulations were used to design a three cavity 36 GHz gyro-klystron of gain 39 dB that is capable of producing 3.2 MW of power corresponding to an efficiency of 43% at a pulse repetition frequency of 1 kHz. Analysis of the phase stability of the amplifier found that 0.34° phase stability can be achieved for a variation in modulator voltage of 0.01%. When driven by a K100 (150kV, 50A) Scandinova modulator, the 36GHz gyro-klystron was a viable power source for a 6th harmonic linearizer.
