Cover illustration: Three-dimensional visualization of the gas-exchanging region of a rat lung, imaged using tomographic microscopy with enhanced field of view at the TOMCAT beamline of the Swiss Light Source (see Haberthür, Hintermüller, Marone, Schittny and Stampanoni, pages 590-599). The transparent parts of the 4 mm-wide rat lung sample on the right show the enhancement in field of view with the proposed method, the magnified inset on the left with a side length of 380 µm shows the details visible in the gas-exchanging region.

The performance of a novel Lu2SiO5 (LSO)-based thin-film single-crystal scintillator for synchrotron-based hard X-ray micro-imaging is characterized. An indirect X-ray imaging detector equipped with such a LSO screen shows improved detective quantum efficiency as well as higher spatial resolving power compared with common scintillator materials.

Increasing the lateral field of view of tomography-based imaging methods greatly increases the acquisition time. This article presents scanning protocols to obtain high-resolution tomographic scans with large lateral field of view at greatly decreased acquisition time and thus reduced radiation dose while resulting in high-quality three-dimensional tomographic datasets.

The atomic local structure of Co-doped ZnO dilute magnetic semiconductors has been investigated before and after annealing by Co K-edge X-ray absorption near-edge structure spectroscopy combined with multiple-scattering calculations to determine the location of oxygen vacancies around magnetic atoms.

Polished surfaces of a naturally heterogeneous mineral sample containing chalcopyrite, pyrrhotite and pentlandite were studied using photoemission electron microscopy (PEEM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS), before and after exposure to aqueous solution.

Secondary focusing with arbitrary source-to-optics distance is analysed based on calculation of `thin lens' focusing in phase space, and the results are compared with tests of a trapezoidal mirror and a single-bounce capillary.

The relative intensities of the maximum K-edge signals of a number of sulfur species in solid state and solution are compared. By use of calibrated reference spectra it is possible to quantitatively determine the relative concentration of different species in an unknown sample.

An advanced intensity normalization technique is proposed, which allows ring and wave artefacts to be suppressed in tomographic images. This is applied to data from beamline 2-BM-B of the Advanced Photon Source.
