Diffraction on a polycrystal for investigations and diagnostics of X-ray radiation of relativistic particles in a forward direction
It is shown that the diffraction on a polycrystal can be used for investigation and diagnostics of X-ray radiation emitted in a forward direction by relativistic charged particles moving in crystalline or other targets or fields. Methods for measuring radiation spectral density, divergence, and linear polarization at any requisite energy from a few units to tens of keV are proposed. The explanation for the origination of experimentally observed and earlier unidentified spectral peaks as a result of Bragg diffraction on a polycrystal is described. The experiment for verification of the explanation is suggested.
