Parametric X-ray radiation (PXR)

Oral

The dynamic theory of coherent X-rays of a relativistic electron crossing a single-crystal target in the Laue scattering geometry is discussed. In [1] Expressions describing the spectral-angular characteristics of radiation in the direction of Bragg scattering are obtained and investigated by the author of the present work. The radiation is considered as a result of coherent addition of the...

Parametric X-ray radiation (PXR)

Oral

The distance between crystallographic planes is of the same order as the X-ray wavelength. For this reason, crystals act as diffraction gratings for X-ray [1]. This interaction is referred as diffraction of real photons. On the other hand, Parametric X-ray Radiation (PXR) has been described as the diffraction of the charged particle Coulomb field in the crystal. This mechanism is referred as...
