Summary: | The Vavilov–Cherenkov effect is a well-known phenomenon widely used in various fields, including the diagnostics of charged particle beams. The possibility of separating Vavilov–Cherenkov radiation (VCR) and luminescent light is critical for the development of a new generation of optical methods in the diagnostics of low-energy beams. This paper presents the first experimental results on the detection of VCR from an electron beam with an energy of 5.7 MeV passing through diamond and corundum (sapphire) crystals. It is shown that Cherenkov and luminescent light have different glow times for a corundum crystal, while these times are comparable for synthetic diamond. The optical scheme implemented in the experiment, consisting of a filter and a polarizer, also makes it possible to separate Cherenkov and luminescent light. The proposed scheme for detecting VCR will be used to develop a new method for measuring the ion beam energy at the NICA facility (JINR, Dubna, Russia). |
