Coherent X-Ray radiation generated by a divergent beam of relativistic electrons in a single crystal in the beam-axis direction

Abstract

A theory of coherent X-ray radiation generated by a beam of relativistic electrons in a single crystal in the direction close to the electron-beam axis is developed in the Laue scattering geometry. The theory takes into account asymmetry of the electron-field reflection with respect to the crystal surface and the electron-beam divergence
