Obtaining accurate lattice parameters from Debye-Scherrer image plate data

An image plate chamber for x-ray diffraction experiments in Debye–Scherrer geometry

A new design for implementation of x-ray diffraction experiments is proposed. The exploitation of the imaging plate technique opens new possibilities to carry out diffraction experiments. The detector chamber in Debye–Scherrer geometry equipped with an image plate takes advantage of this technology such as high resolution, high sensitivity, linearity in intensity, and linearity over the detecto...

Influence of Image Processing Conditions of Debye Scherrer Ring Images in X-ray Stress Measurement Using an Imaging Plate

ABSTXACT This paper describes the study of the possibility of x-ray stress measurement in which stresses are obtained by analyzing the whole of one diffraction ring detected with a two-dimensional x-ray detector called an imaging plate (IP). The theory of the stress determination proposed by Taira et al (1978) was shown and advanced to make measurable all plane stress components. The experiment...

Estimating Debye Parameters from GPR Reflection Data Using Spectral Ratios

In the GPR frequency range, electromagnetic wave attenuation is largely controlled by dielectric relaxation processes. A primary relaxation commonly occurs in the 10 – 100 MHz range for many earth materials in which the GPR signal propagates effectively. This relaxation leads to strong nonlinearity in the frequency dependent attenuation and occurs in a frequency range that is often used for gro...

Lattice Parameters and Debye Temperature of Naclx Nabry-X Kcl1-

Mixed crystals of alkali halides find applications in optical, optoelectronics and electronic devices. In the present study the pure and mixed crystals of NaClx NaBry-x KCl1-y were grown from the aqueous solution. The grown crystals were characterized by taking XRD, TG/DTA and Vicker’s hardness measurement. The Debye temperature is an important parameter of a solid. Several methods of evaluatin...
