Research of the polarization bremsstrahlung of relativistic electrons in polycrystalline targets

Abstract:

The collimated spectra of polarization bremsstrahlung (PB) produced by 7 MeV electrons in Al, Ni, Cu, Mo and W poly crystalline foils are measured and the angular dependences of the PB characteristics are studied. A comparison of the experimental results with theoretical pbkp_redictions is performed. Polarization bremsstrahlung sensitivity to texture and grain size of the target in the backscattering geometry is shown. The possibility of developing a new method based on the characteristics measurement of the coherent PB component for the diagnostics of polycrystalline materials is considered.
