Estimation of Crystal Sample Structure by Means of Fast Electron Radiation

An analysis is made of the dependence of the characteristics of X-ray radiation arising during the passage of fast electrons through the crystal on the quality of the internal structure of the sampleyesBS

Influence of crystals mosaicity on observed characteristics of X-ray emission along the propagation velocity of fast electrons in thick tungsten crystals

The results of a set of experiments on X-ray emission yield of ω ∼ γωp energy, generated by 500MeV energy electrons in oriented tungsten single crystals are presented. The experiments were performed at Tomsk synchrotron using Crystal grating spectrometers based on mosaic crystals of pyrolytic graphite. It is shown that the measurement results are caused by the competition of two mechanisms: parametric X-ray emission along the particle velocity and bremsstrahlung diffraction in mosaic crystals of aα group. A method for determining the characteristic bulk dimensions in mosaic crystals of aα group is suggested

Calculation of class-b mosaic crystals reflectivity by Monte Carlo technique

Mosaic crystals of b-type, for example, pyrolytic graphite, is widely used in experimental physics as neutron and X-ray monochromators and provide a higher yield of monochromatic radiation than perfect ones.
