Grazing incidence X-ray diffraction data of samples with different textures and MATLAB code for their evaluation

1. Graz University of Technology

This data set contains grazing incidence X-ray diffraction (GIXD) data of LaB6 thin films, anthracene thin films, and a fluorapatite single crystal measured at the XRD1 beamline Elettra Trieste. The LaB6 thin films feature crystallites with random orientation (3D powder) and the anthracene crystallites have a uniaxial texture (2D powder). Due to the different types of textures, the measurements of each sample require a different evaluation procedure in order to obtain reliable intensities from the Bragg peaks visible in the GIXD patterns. Therefore, a MATLAB code to perform this type of evaluation is provided together with the data set.

Technical info (English)

GIXD data was measured with X-rays at a wavelength of 1.4 A on a Dectris Pilatis 2M detector at a sample-detector distance of 200 mm. Samples were rotated around their surface normal during the measurements. For the transformation of the data to reciprocal space an LaB6 calibrant was measured. The corresponding files are also included in the data set.
