The phase shift of forward-diffracted X-rays by a perfect crystal is discussed on the basis of the dynamical theory of X-ray diffraction. By means of a triple Laue-case X-ray interferometer, the phase shift of forward-diffracted X-rays by a silicon crystal in the Bragg geometry was investigated.

Laue Geometry

Recently using the theory of Afanasev-Aginian (1977-1978) it has been reconsidered theoretically the properties of the contributions of PXR, DTR and their interference into the radiation intensity produced by particles in single crystals in Laue geometry, essentially differing from those of Bragg geometry. After a short review of theoretical and experimental works devoted to DTR in this work we discuss the properties of Laue geometry and make comparison of the predictions of the above theory with the results of the second experiment performed by Avakian et al in 1987 with the help of 4.5 GeV electrons.

X-ray Bragg diffraction in sagittal geometry on a Y-cut langasite crystal (La3Ga5SiO14) modulated by Λ = 3 µm Rayleigh surface acoustic waves was studied at the BESSY II synchrotron radiation facility. Owing to the crystal lattice modulation by the surface acoustic wave diffraction, satellites appear. Their intensity and angular separation depend on the amplitude and wavelength of the ultrasonic superlattice. Experimental results are compared with the corresponding theoretical model that exploits the kinematical diffraction theory. This experiment shows that the propagation of the surface acoustic waves creates a dynamical diffraction grating on the crystal surface, and this can be used for space–time modulation of an X-ray beam.
