Coherent X-radiation along the velocity of a relativistic electron in a bounded periodic multilayer medium

Manifestation of the effects of dynamic diffraction in the coherent X-ray radiation of relativistic electrons in a periodic layered medium

“…We note that, in all cited papers , the process of emission in a periodic layered medium was regarded only in the Bragg scattering geometry in the case of symmetric reflection, where the angle between the surface and reflecting planes was zero and emitted photons escaped through the front target boundary. The authors of [23][24][25] developed the dynamic theory of the coherent X ray radiation of relativistic electrons in periodic layered media in the general case of asym metric reflection of the electron field with respect to the target surface, i.e., when reflecting target layers were located at a certain angle to the target surface.…”
