Observation of the fine structure of X-ray interference patterns from double- and triple-crystal systems

Abstract

The results of experimental and theoretical investigations of the X-ray diffraction patterns from double- or triple-crystal systems and a thick absorbing crystal are presented. The period of the fringe patterns from the double-crystal system is calculated. An expression for calculating the linear enlargement factor in the presence of a crystal-magnifier is deduced. It is proved that the crystal-magnifier does not change the interference pattern but only increases its angular sizes in the scattering plane.
