The lowbitron—a longitudinal wiggler beam interaction device—as a novel source of submillimeter wave radiation was proposed and analyzed theoretically by McMullin and Bekefi [Phys. Rev. A 25, 1826 (1982)]. This letter reports the first experimental measurements of lowbitron radiation obtained with a 740-kV, 400-A electron beam. The measured power spectra in the W-band range for different wiggler field periods agree with the lowbitron interaction theory. They match the intersection points of the shifted fast cyclotron wave dispersion relation ω-(k+kw)v||-Ω0/γ=0 and the TE01 electromagnetic waveguide mode.
