Beam Handling by Crystals

Abstract

Using channeling phenomena of a crystal is one of the useful ways to handle high energy beams efficiently. We have performed an experiment with a 150–MeV electron beam at Hiroshima University and one with a 12–GeV proton beam at KEK–PS. In this article, these experiments are presented. In addition, examples of applications of bent crystals, such as a possibility of beam collimation at the ILC and a beam separation device at J–PARC, are briefly introduced.
