Polarized breamsstrahlung generated by interaction ion beam and some crystals

Polarized breamsstrahlung (PB) of relativistic particles in the crystal become more interesting object as a theory as an experimental investigation. Such interest connected with the essentially changes of the traditional representations about interaction the relativistic particles and periodical structure of the crystal. Object of research of this theory are the radiation presses of a fast particle interaction with the collective of atoms, when the properties of a radiating photons are determined simultaneously as a character of interaction of previously particles with separate atoms, as interatomic by correlations. In the certain conditions the coherent exit of radiation on all collective of atoms can considerably exceed an incoherent background. Thus opens ample opportunities to diagnostics a structure of substance and a creation of effective sources of X-ray radiation with unique parameters on intensity, orientation and monochromatic. The experimental setup investigation polarization breamsstrahlung generated by interaction of hydrogen ions with the atoms of different targets are described. The ion beam was generate by the heavy current pulse accelerator IBM-50 (energy H ⁺=20 keV, current of ions pulse Ipulse=10 A, pulse length=10mkS). The received results are in the qualitatively agree with the theoretical data.
