Summary:	Title screen Studies of the spectral and kinetic characteristics of CaF2, BaF2–Ce, LiF, LiF–W and MgF2 crystal glow irradiated by the electron beam with energy of 350 keV have been carried out. It has been shown that the cathodoluminescence spectrum of CaF2 and BaF2–Ce consists of high-intensity exciton bands in the UV-region of the spectrum, the radiation time of which exceeds the duration of the electron beam current. Radiation of the LiF and LiF–W crystals also has exciton bands in the UV-region, but their transmittance decreased during the excitation pulse due to accumulation of radiative defects. It has been found, that the MgF2 crystal has the lowest cathodoluminescence intensity. This has allowed us to distinguish Cherenkov radiation the duration of which corresponds to the electron beam current duration in the wavelength range of 240–400 nm.
