Abstract :
A Cherenkov FEL can be a suitable source for radiation from the millimeter wavelength region down to the far infrared. With only a few different dielectric materials the laser can range from 6 mm down to ≈ 600 μm. Nonlinear theory shows, for an amplifier configuration, power levels of about 100 kW in the far infrared up to several MW at millimeter wavelengths. Good coupling with the evanescent wave supported by the dielectrically lined waveguide requires a thin walled annular beam of good quality. The characteristics of such an electron gun, a special design for a Cherenkov FEL with parameters given in this paper, will be presented.
