Pulse X-ray diffraction study of shock-compressed NaCl

Results of X-ray diffraction study of shock-compressed NaCl single crystals of ≪100≫ orientation are suggested. A new geometry of X-ray diffraction survey specially developed for studies of a single crystal sample in the monochromatic radiation was employed to obtain a multi-peak diffraction pattern allowing the complete determination of the components of the crystal strain tensor. During the compression of the crystals their state was continuously monitored by velocity interferometer. The diffraction patterns obtained at the different regions of the plastic wave front evident the crystal is able to maintain the state of unidimensional compression up to the strain level of about 0.06.
