We report on the application of a new, non-dispersive double multilayer optical arrangement to prepare a parallel beam from a laboratory x-ray source for standardization of powder diffraction reference materials and the associated high accuracy diffractometer. The beam preparation optic uses a graded-spacing parabolic multilayer to gather radiation from a small focus x-ray source and a subseque...

Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrysta...

A compact detection module for the simultaneous measurement of XRF and XRD in portable analytical applications, particular mining sector, is presented. The detector head based on 32 silicon strip detectors, fabricated with a low-leakage technology by FBK readout two 16-channel low-noise CUBE charge-sensitive amplifiers. design its characterization are reported. Multiple configurations experimen...

Backscattering spectrometry, x-ray diffractometry, and scanning electron microscopy have been used to study the reaction of a thin Pt film with an epilayer of ^110& GaN on ^110& sapphire upon annealing at 450, 550, 650, 750, and 800 °C for 30 min. A Ga concentration of 2 at. % is detected by MeV He backscattering spectrometry in the Pt layer at 550 °C. By x-ray diffraction, structural changes a...

Experimental results of the study of the mineralogical characterization of coals by X-Ray differaction and IR are reported. These results suggest that different minerals present as major and minor phases in the coals could be distinctly characterised by X-ray diffractometry. The IR spectroscopy technique has provided additional supplementry informations for the identification of several other m...
