Measuring coherent peaks of polarization bremsstrahlung from relativistic electrons in polycrystalline targets in backscattering geometry

The spectra of polarization bremsstrahlung (PB) in the X-ray range induced by 7-MeV electrons in a polycrystalline copper target have been measured in the backscattering geometry for various orientations of the target relative to the electron beam. It is shown that the PB backscattering is sensitive to the texture of a target. The possibility of developing a new method based on the measurement of characteristics of the coherent PB component for the diagnostics of polycrystalline materials is considered.
