Paper Abstract

Experimental observations of refraction/small angle scattering of synchrotron radiation from non-crystalline materials are reported and discussed. This technique constitutes a further application of an experimental-analytical x-ray phase retrieval technique previously utilized for Bragg diffraction data. The recent impetus for these studies arose from high resolution measurements of x-ray refraction phenomena from a narrow aperture performed in the laboratory, which suggested that the phase retrieval formalism could also be applied to non-crystalline materials. The experiments were performed using bending magnet sources at the European Synchrotron Radiation Facility (ESRF) in France, and the Photon Factory, Japan. Refraction/small-angle scattering data was collected from thin (20 - 125 micrometer) filaments of optical fiber (silica), copper, nylon6, kapton and human hair. The experimental results obtained are in close agreement with theoretical simulations. Successful application of the phase retrieval formalism to this data will establish a basis for a novel materials characterization technique.
