The choice of this energy range is related to the potential application of the results for the design of a new accelerator complex at the NSC KIPT. Using numerical simulations, orientation effects in the scattering of electrons and positrons with energies of 500 MeV and 1 GeV in oriented crystals were considered. The analysis showed that in a straight crystal with planar orientation, the largest deflection angles for both electrons and positrons can be achieved when the particle incident angle corresponds to the critical angle of planar channeling. In a silicon crystal with a thickness of 100 µm, the deflection angles in this case reach several milliradians. In the case of axial orientation of the crystal, the deflection angles are slightly larger and are mainly due to ring-like and incoherent scattering. It was also shown that scattering of particles in a bent crystal allows for significantly larger deflection angles of charged particles than in a straight crystal. For positrons, the most effective deflection for particles with energies up to 1 GeV was achieved with planar orientation of the (110) crystal plane. In contrast, for electrons, stochastic deflection realized under axial orientation of the crystal turned out to be the most efficient mechanism for particle deflection, allowing a much larger number of particles to be deflected to a given angle compared to planar channeling.
