A noninvasive technique to determine a sub-mm length of electron bunches (rms < 100 um) based on a measurement of the coherent Cherenkov radiation spectrum in THz range is proposed. The radiation is generated while electron bunch moves in a vacuum near dielectric target. If the optical properties and geometry of a target are chosen in order to achieve a low absorption with a dispersion allowing expanding the Cherenkov cone, such target may be considered as the natural Cherenkov prism. We demonstrate a feasibility of using of CsI prism for measurement of a bunch length in the range 50-200 um for Lorentz factor γ = 100. We also measured coherent Cherenkov radiation power from Teflon target generated by the 6.1 MeV bunched electron beam with bunch rms length 1.2 mm. CChR seems to be a promising radiation mechanism for a new beam diagnostics technique.
