The results received in work show, that the stochastic mechanism of the charged particle deflection by bent crystals with particle momentum growth up to 1 ТeV/с does not lose the efficiency. This mechanism enables deflection of both positively, and negatively charged particle beams on angles that considerably exceed the critical angles of plane and axial channeling. The stochastic mechanism of particle deflection can be used for charged particle beam collimation and for beam splitting on several parts. The carried out simulation has shown, that though efficiencies of proton and pi-minus meson beams deflection are almost identical, the scattering of particles essentially depends on a sign of particle charge. This discrepancy is connected with the fact that protons after escape from the stochastic deflection regime go to the bent plane channels and continue motion in the plane channeling regime. For pi-minus mesons the dechanneling length is much smaller than for protons, therefore pi-minus mesons after escape from the stochastic deflection regime remain in above-barrier regime and cease to deflect.
