Crystalline undulator radiation of microbunched beams taking into account the medium polarization

Abstract

Analytical and numerical results are obtained on the angular and spectral distributions of the number of photons as well as on the total number of the photons of the coherent X-ray crystalline undulator radiation (CXCUR) produced by microbunched beams passing through crystalline undulators (CU). These results show that one can use CXCUR for study of the microbunching process in XFELs and for production of additional monochromatic intense beams.
