Observation of a variable sub-THz radiation driven by a low energy electron beam from a thermionic rf electron gun
We report observations of an intense sub-THz radiation extracted from a ∼3 MeV electron beam with a flat transverse profile propagating between two parallel oversized copper gratings with side openings. Low-loss radiation outcoupling is accomplished using a horn antenna and a miniature permanent ma...
