Diffraction of X-ray Pulse in Crystals
Recently the investigation of the extremely short (subpicosecond) X-ray pulses interaction with crystals takes interest because of the development of linac-driven X-ray Free Electron Laser, operating in the SASE mode and X-ray Volume Free Electron Laser [1, 2]. According to the analysis [3] short X-ray pulse passing through a crystal is accompanied by the significant time delay of radiation. Th...
متن کاملTemperature-Dependent X-ray Diffraction Measurements of Infrared Superlattices Grown by MBE
Strained-layer superlattices (SLSs) are an active research topic in the molecular beam epitaxy (MBE) and infrared focal plane array communities. These structures undergo a >500 K temperature change between deposition and operation. As a result, the lattice constants of the substrate and superlattice are expected to change by approximately 0.3%, and at approximately the same rate. However, we pr...
متن کامل[4] X-Ray Diffraction of Protein Crystals
The X-ray study of protein crystals is a difficult and highly specialized field. Eventually, when the structure of a few proteins has been unraveled, the results will be of vital interest to ensytiologists, since they should give information about the spatial arrangement of the “active site” of the enzyme. But meanwhile X-ray methods will have only a secondary interest for enzymologists. The eq...
متن کاملCompressibility of lysozyme protein crystals by X-ray diffraction.
Single-crystal high-pressure X-ray diffraction studies on the protein crystals of orthorhombic and tetragonal hen egg-white lysozyme polymorphs were carried out using a Merrill-Bassett diamond-anvil cell, image-plate detector and synchrotron radiation. The orthorhombic crystal has been squeezed to 85.5% of its ambient pressure volume at about 1.0 GPa; the crystal compresses anisotropically, and...
متن کاملReal-time, high-resolution x-ray diffraction measurements on shocked crystals at a synchrotron facility.
The Advanced Photon Source (APS) at Argonne National Laboratory was used to obtain real-time, high-resolution x-ray diffraction measurements to determine the microscopic response of shock-compressed single crystals. Disk shaped samples were subjected to plane shock wave compression by impacting them with half-inch diameter, flat-faced projectiles. The projectiles were accelerated to velocities ...
