Particle channeling in a bent crystal

Abstract

The channeling of high-energy charged particles in bent crystals is being used more and more extensively for steering particle beams at accelerators, for extracting a beam or its halo from an accelerator, and for splitting the extracted beam. The use of the strong intracrystalline fields of bent crystals in high-energy physics, for example, to measure the magnetic moments of short-lived particles from the spin precession angle in a bent crystal, appears to be very promising. The results of studies on the channeling of high-energy particles in a bent crystal are reviewed. The features of channeling and quasichanneling, the ionization energy losses, and the radiation emitted by channeled particles are studied. The possibility of polarization effects for channeled particles is discussed.
