A novel epitaxially grown LSO-based thin-film scintillator for micro-imaging using hard synchrotron radiation

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.

Local structure of vanadium in doped LiFePO₄

Radiation dose optimized lateral expansion of the field of view in synchrotron radiation X-ray tomographic microscopy

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.

Investigation of annealing-induced oxygen vacancies in the Co-doped ZnO system by Co K-edge XANES spectroscopy

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.

Synchrotron PEEM and ToF-SIMS study of oxidized heterogeneous pentlandite, pyrrhotite and chalcopyrite

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.

A high-repetition-rate mechanical X-ray shutter, with complete asynchronous control, has been developed and tested to achieve closing speeds as fast as 700 µs for an aperture height of 4 mm.

High-resolution soft X-ray beamline ADRESS at the Swiss Light Source for resonant inelastic X-ray scattering and angle-resolved photoelectron spectroscopies

Concepts and technical realization of the high-resolution soft X-ray beamline ADRESS at the Swiss Light Source are described. Optimization of the optical scheme for high resolution and photon flux as well as diagnostics tools and alignment strategies are discussed.

Phase-space analysis and experimental results for secondary focusing at X-ray beamlines

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.

K-edge XANES analysis of sulfur compounds: an investigation of the relative intensities using internal calibration

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.
