In the report we present simulation results for angular distributions of the radiation as well as spectral distributions obtained by the PiC code KARAT for the conditions of the experiment . We show that for strict satisfaction of the condition θcone=θCR/2 (θcone is an opening cone angle, θCR=arcos 1/βn) is the Cherenkov angle, β =v/c, n is a refractive index) a propagating radiation beam is retained a hollow structure for distances much larger than a radiator length. We simulated "radii"of such a structure at different distances from an exit radiator surface and estimated a divergence of the Cherenkov radiation (CR) beam.
