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
Calculation of the X-ray reflectivity of b-class mosaic crystals via the Monte Carlo method
b-class mosaic crystals, including pyrolytic graphite, are widely used as neutron and X-ray monochromators in experimental physics and ensure a more intense yield of monochromatic radiation than do perfect crystalsye
Influence of crystal mosaicity on the X-radiation characteristics observed at a small angle to the particle velocity direction
The experimentally measured yields of X-rays generated by 500-MeV electrons in oriented tungsten single crystals are analyzedye
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 Ο βΌ Ξ³Οp 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 aΞ± group. A method for determining the characteristic bulk dimensions in mosaic crystals of aΞ± group is suggested
Calculation of class-b mosaic crystals reflactivity by Monte Carlo techniqye

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. The technique is proposed and implemented to calculate the reflectivity of such crystals by Monte Carlo modeling, correctly considering the multiple reflections of photons inside the crystal and the geometry of experiment for random distribution of the mosaic
