Orientational coherent interactions in crystals for manipulation of charged-particle beams and for the generation of hard gamma quanta.
Coherent effects in bent crystals are a powerful method to manipulate the trajectories of charged particles in accelerators within a very wide energy range, spanning from 1 MeV to 6.5 TeV. Special tailoring of crystals enabled to attain particle deflection up to the theoretical limit, which in the same cases includes most of the particle in the beam. Coherent interactions of electrons or positrons proved capable of generating intense gamma quanta far harder than it would be possible through bremsstrahlung with primary particles at the same energy. We review the state-of-the art of research with special attention to possible applications in accelerators.
