Abstract

The motion of relativistic nuclei through an oriented bent crystal was considered on the basis of a developed computer code. To get the angular distributions of projectiles behind the crystals and to estimate the influence of multiple scattering on beam deflection, a detailed study of the beam dynamics due to the processes of channeling, dechanneling and quasichanneling of the particles is presented. The analysis of the beam redistribution in a crystal was performed simulating the main features of the scattering of relativistic Pb ions and protons in the field of bent crystal planes. The comparison of simulated data with experimental ones has been also carried out.
