The conical effect in Smith-Purcell radiation arising from electrons moving at non-zero angle ψ to the direction of grating periodicity has been observed for the first time. It was found that the maximum of radiation intensity for ψ ≠ 0 shifts in both polar and azimuthal angles. The experimental and theoretical results were compared, and the good agreement was shown. The experiment has been performed for 6MeV electrons and at millimeter wavelengths.
