Powerful high-efficiency FEM-amplifier operating over Ka frequency range and aimed on accelerating applications is developed in collaboration between IAP RAS and JINR. To achieve a broad amplification band in a regular wiggler, we utilized the so-called grazing regime, in which about of 20 MW of output power was simulated in the frequency range of 30 ± 3 GHz. In the first stage of experiments, the designed power level and the instantaneous band of about 1 GHz (restricted by the tuning band of the driving magnetron) have been demonstrated. According to the simulations, the use of the regime of non-resonant trapping in tapered wiggler allows enhance in the output power up to 35–40 MW with simultaneous widening of the amplification band. Experimental realization of this novel FEM-amplifier scheme is currently in progress.
