A high repetition rate compact 94GHz free electron laser

The motivation for this work is to operate a practical free electron laser (FEL). The total volume of this device, including the accelerator and its modulator, is only 5 m³. The maximum duty cycle is 0.2% and the predicted peak power is 10 kW. The electron beam accelerator is a simple standing-wave RF-linac driven by a 5 MW. 1.3 GHz magnetron. The linac will accelerate electrons to an energy of up to 2 MeV at a micropulse current of 100 A with an average macropulse current, I, of 1 A. The initial two experiments will be an FEL amplifier and an FEL oscillator at 94 GHz.
