Experimental study of an FEM with a microwave system of a new type

Operability of the wide-band reflector based on the effect of microwave beams multiplication was tested in the "hot" experiment. A microwave system of the new type including such a reflector was used in a free electron maser (FEM)-oscillator with a guide magnetic field. The high-current ac...

Description
Summary:Operability of the wide-band reflector based on the effect of microwave beams multiplication was tested in the "hot" experiment. A microwave system of the new type including such a reflector was used in a free electron maser (FEM)-oscillator with a guide magnetic field. The high-current accelerator "Sinus-6" forming a 500 keV/120 A electron beam was used as the FEM driver. The double-resonance regime, when both the undulator and the cyclotron resonance conditions were fulfilled simultaneously, provided maximum output power 7 MW and electron efficiency 12% at the designed frequency 45 GHz.
