Abstract
Section titled “Abstract”The interest in studying characteristics of the Vavilov-Cherenkov radiation (VCR) increased in connection with works on creation of runaway electron (RE) detectors for tokamak type facilities. The survey presents results of investigations of spectral, amplitude-time, and spatial VCR characteristics obtained mainly in recent years upon excitation of transparent substances by a flux of electrons with energies of tens or hundreds of kiloelectronvolts. The VCR spectra in diamond (natural and synthetic), quartz glass, sapphire, and leucosapphire are presented. It is reported about VCR detection in MgF2, Ga2O3, and other transparent samples. The spectra and amplitude-time characteristics of VCR and pulsed cathodoluminescence (PCL) are compared at different electron energies. For some samples, VCR spectra are calculated with allowance for dispersion of the refractive index, as well as energy distributions of beam electrons and decreases in energy of electrons in the process of their deceleration in the substance of the samples. The emission spectrum of polymethylmethacrylate (PMMA) which is used as a material for radiators in Cherenkov detectors and lightguides transmitting the radiation in scintillation dosimeters and as a plastic base in organic scintillators is studied.
