Abstract :
The first stage of the experimental study of a frequency adjustable FEM-oscillator with a broadband microwave system based on the effect of microwave beams multiplication is presented. Operability of the key element of this system (wide-band reflector) was tested in the “hot” experiment. The 45 GHz FEM-oscillator with a microwave system of the new type was driven by a 500 keV, 120 A, 20 ns electron beam and generated 7 MW of radiation with a 12% efficiency. A new double-resonance operating regime of the FEM with combined - undulator and homogeneous guide - magnetic field, when both the undulator and the cyclotron resonance conditions are fulfilled simultaneously, was realized.
