Optical Cherenkov Radiation from a Transparent Plate for Beam Diagnostics / A.Potylitsyn, A.Baldin, Vit.Bleko, Ver.Bleko, V.Kobets, M.Nozdrin, [a.o.]. – Text : electronic // Radiation Physics and Chemistry. – 2026. – Vol. 243. – P. 113708. – URL: https://doi.org/10.1016/j.radphyschem.2026.113708. – Bibliogr.: p. 113708-(7-8).
Optical beam diagnostics based on transition radiation (TR) is widely used to measure both transverse and longitudinal bunch sizes. However, in installations based on modern acceleration techniques (laser-plasma, etc.), the intensity of the beam may be insufficient for TR diagnostics. The application of alternative, more intense radiation mechanisms will improve the accuracy of optical diagnostic methods, particularly in lowintensity beam diagnostics. This article presents the results of detailed studies comparing the characteristics of Cherenkov radiation (ChR) with traditional TR in the context of beam diagnostics. The experiment was carried out using an electron beam from the accelerator with an energy of 18 MeV. Radiation detection was performed at an angle of 90◦ relative to the electron beam using the TAMRON lens with a focal length of 18÷ 400 mm and a CMOS camera. The TR and ChR targets used were an aluminized silicon wafer and a corundum plate (0.5 mm thickness). When focusing ‘‘on the target’’, the dimensions of the ‘‘light footprint’’ of a collimated electron beam with a diameter of 5 mm on both targets were measured. The shape of both footprints was approximated by a Gaussian in the horizontal and vertical directions with the parameters *s&sub(x) = 1.83, *s&sub(y) = 1.67 mm (TR target) and *g&sub(x) = 2.24 mm and *s&sub(y) = 5.41 mm (ChR radiator). As a result, the ratio between the photon yield of TR and ChR was 1 ∶ 9.7. This result agrees reasonably with the theoretical calculations.
