Description

Previously, in [1-6], it was experimentally shown that the quasi-monochromatic radiation is generated when an electron beam interacts with a multilayer structure of an X-ray mirror in the direction of the Bragg diffraction. The spectrum of this radiation depends on the period of the structure and the tilt angle of the target relative to the electron beam. Here we present the results of the experimental and numerical studies of the angular distributions of this type of radiation in the ultra soft X-ray region (50÷150 eV) for a wide range of the target tilt angles, upon irradiation of a [Mo/Si]50 structure with a period of d=11.32 nm by electrons with an energy of 5.7 MeV. The comparison of the experimental data with the results of calculations following the theory [1, 2] has been done.
