Small Angle X-ray Scattering in Thin Iron Films [PDF]

Журнал нано- та електронної фізики, 2014
By small angle X-ray scattering (SAXS) and atomic force microscopy characteristic sizes are determined, structural features of thin iron films deposited by magnetron evaporation onto substrates from pyroceramics are established.

Varying Collimation for Dark-Field Extraction

International Journal of Biomedical Imaging, 2009
Although x-ray imaging is widely used in biomedical applications, biological soft tissues have small density changes, leading to low contrast resolution for attenuation-based x-ray imaging. Over the past years, x-ray small-angle scattering was studied as
