Polarization Bremsstrahlung by Relativistic Electrons in Backscattering Geometry for Diagnosing Atomic Structure of Polycrystals

The measurements of X-ray polarization’s bremsstrahlung in the back scattering geometry (PBBS) generated during the interaction of 7 MeV electrons with polycrystalline foils of copper and niobium were performed. The analysis has shown a good agreement of the spectral width and position of the peaks with the theoretical calculations. The obtained results confirm the availability to develop a new method based on the PBBS peaks measurements for diagnostics of materials with a polycrystalline atomic structure.
