Coherent Radiation of Crystalline Beams

Crystallization and radiation of accelerator beams is considered. For the first time it is shown that crystallization conditions for charged particle beams differs from those of plasma. Crystallization conditions of charged relativistic bunches are found and shown that they may be satisfies in existing linacs. The coherence radiation of crystalline beams in the XUV region is investigated. Necessary conditions of coherency are found. The influence of deviations from mean interparticle distance on the radiation coherency is considered.
