Prospects of application of the focusing crystals at the large hadron colliders

摘要

Ideas of use the particle channeling in bent crystals for steer the beams have been checked up and advanced in many experiments. However, until now, this method of beam formation has limitations in application, since the channeling process involves beam particles with low angular divergence, limited by the angle of Lindhard. Here we describe the focusing crystals, which expand the boundaries of application of bent crystals at accelerators.
