The excitation of the wake field by a laser pulse in an ionic dielectric has been considered. The frequency spectrum of Cherenkov radiation is determined, the spatial-temporal structure of the Cherenkov electromagnetic field has been obtained and studied. The problem of self-injection of electron bunches in the wake acceleration method during excitation of the wakefield in plasma by two laser pulses has been investigated by numerical simulation. It is shown that at one wavelength between laser pulses only one bunch is self-injected after the last laser pulse, and at two wavelengths between pulses, the bunches are self-injected after each laser pulse. The dynamics of the high-current ion beam in the system of magnetic casps and accelerating gaps in each casp with additional azimuthally homogeneous injection of relativistic electron beams for charge and current compensation has been studied using the 3D code "Karat".
