Highlighted illustration

Cover illustration: Pole figures depicting the angular change of lattice plane normals for four applied deformations (see Poshadel, Dawson and Johnson, pages 237-244). These images illustrate how insufficient pole figure coverage introduces ambiguity between correct and other plausible deformation modes, which inherently limits component-wise resolution of the strain tensor.

Basic and application studies of grazing-incidence synchrotron-radiation 57Fe-Mössbauer spectroscopy using a nuclear Bragg monochromator are introduced. As a great advantage for surface and interface science, the developed method combined with the 57Fe-probe layer technique enables researchers to study the interface structure of thin films with atomic-scale depth resolution.

Optimized X-ray waveguides have been fabricated and characterized in terms of transmission, angular acceptance, farfield pattern and imaging applications. Beam confinement down to sub-10 nm in two orthogonal directions has been demonstrated, at the nano-focus endstation at P10 of PETRA III at HASYLAB/DESY.

An in situ loading experiment demonstrates differences in uncertainties among deviatoric lattice strain components measured using polychromatic X-ray microdiffraction. Monte Carlo simulations show that the differences in uncertainties are caused by spurious deformation modes that arise erroneously in the strain calculation owing to measurement noise and limited pole figure coverage.
