On the possibility and effectiveness of the phenomenon of quantum-braking self-modulation and self-bunching of the charged particle beams at coherent channeling of non-modulated beams in perfect thin complex crystal

Considers the problem of nonthreshold quantum-deceleration self-modulation (in space and time) of the charged and noncharged particle beams at coherent channeling in thin perfect oriented crystal. The results of investigation of the efficiency and optimization methods of the phenomenon of charge particle beam self-modulation behind the perfect thin complex crystal are discussed. The phenomenon of nonthreshold quantum braking quasi-monochromatic self-modulation of a particle beam is a result of the difference (in result of different transversal braking in adjacent (alternating) channels of perfect complex crystal) of total energies and longitudinal impulses of particles (electrons) after channeling inside the region of their mutual coherence and nonstationary interference of this particles eigenfunctions behind the crystal.
