A two-dimensional waveguide beam for X-ray nanodiffraction

A characterization of the X-ray beam generated from differently sized two-dimensional waveguides was performed, giving values for the beam geometry, the transmission efficiency and absolute fluxes. A first high-resolution nanodiffraction experiment using the beam out of a two-dimensionally confining waveguide was performed on a nanocrystalline TiN hard coating in order to reveal the local gradients across the blasted coating.
