XIII International Symposium RREPS-19, 15-20 September 2019, Belgorod, Russia 75Optical Cherenkov Radiation from an Inclined Plate as aTool for Angular Beam DiagnosticsA.Potylitsyn1, A.Vukolov, B.Alexeev, T.AtovullaevNational Research Tomsk Polytechnic University, Tomsk, RussiaIn the paper [1] authors presented results of the measurements of the opticalCherenkov radiation generated by 255 MeV electrons passing through an inclineddiamond plate with a thickness 50 micrometers. They showed that intensity of theregistered photons (a part only from the whole Cherenkov cone, which is extractedinto vacuum from the inclined plate) is high enough for certain detection.We propose to use such an effect to determine a beam divergence measuring adependence of the Cherenkov radiation yield on the inclination angle for a fixeddetector position.For electron energy ∼ 1 GeV and the quartz plate thickness 4 mm it is possibleto measure a divergence at the level 10−4 rad.This work was supported by the grant of the Ministry of Science of the RussianFederation (Project # 3.1903.2017).References[1] Y.Takabayashi, E.I.Fiks, Yu.L.Pivovarov, Phys.
