Stimulated undulator radiation in a high-efficiency regime
Abstract
The generation of stimulated H(01)-mode undulator radiation using a gyrotron-type cylindrical resonator of quality factor 1500-2000 on the SINUS-6 accelerator (El'chaninov et al., 1981) is reported. Techniques proposed to stimulate undulator emission of relativistic electrons are reviewed and the experimental setup is briefly characterized: the undulator employs 2N coils with alternating winding direction to provide adjustment of the radial component of the magnetic field from 0 to 3 kOe while maintaining the uniform field at 9-10 kOe, and tuning to synchronization is achieved by varying the electron energy in the range 450-680 keV at beam current 3-5.5 kA. The results are presented in graphs, and generation of maximum power 300 MW at wavelength 18 mm is achieved in 10-15 ns at an efficiency of 10 percent or more.
