A 48GHz gyroklystron amplifier has been designed using particle-in-cell (PIC) simulation techniques. The beam is provided by a magnetron injection gun (MIG). The gyroklystron is predicted to deliver 2MW of output power at 48GHz with a gain of 35dB and an efficiency of 38%. The design was developed with consideration of the harmonic linearizer of a linear accelerator (linac) that is being designed as part of the H2020 CompactLight X-ray free electron laser (XFEL) project.
