Modelling an Energy-Dispersive X-Ray Diffraction System for Drug Detection

Energy-dispersive X-ray diffraction using an annular beam.

We demonstrate material phase identification by measuring polychromatic diffraction spots from samples at least 20 mm in diameter and up to 10 mm thick with an energy resolving point detector. Within our method an annular X-ray beam in the form of a conical shell is incident with its symmetry axis normal to an extended polycrystalline sample. The detector is configured to receive diffracted flu...

Development of Fast Texture Mapping System with Energy Dispersive X-ray Diffraction Method

Texture mapping system with energy dispersive X-ray diffraction method has been newly developed. Total time of measurement was reduced more than half by the adoption of a fast data transmission interface. Some examples are demonstrated in order to show the performance of the system. This approach is suitable for the study of local inhomogeneities of texture, such as colonies, in polycrystalline...

Introducing an Optimized Method for Obtaining X-ray Diffraction Patterns of Biological Tissues

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...

Energy dispersive X-ray diffraction to identify explosive substances : spectra analysis procedure optimization

To detect the presence of explosives in packages, automated systems are required. Energy dispersive X-ray diffraction (EDXRD) represents a powerful non invasive tool providing information on the atomic structure of samples. In this paper, EDXRD is investigated as a suitable technique for explosive detection and identification. To this end, a database has been constructed, containing measured X-...
