    "abstract": "Using the pre-bunched electron beam of 5-MeV linear accelerator the coherent\nSmith-Purcell radiation (CSPR) from a flat periodic target (made of conductive\nlayers separated by dielectric gaps) in millimeter wavelength region has been\ninvestigated. The angular distribution of this radiation was measured with a\nnarrow-band detector and experimental data agree with our theoretical\ncalculations for similar kind of targets. Such properties of Smith-Purcell\nradiation as strong dependence of radiation wavelength on the observation angle\noverlapping with coherent radiation effect may be used for a noninvasive bunch\nlength measurement. The possibility of using the room temperature detectors for\nsingle bunch measurements is demonstrated.",
