Performing an x-ray scattering analysis can underpin the quantitative description of a sample of interest, for example, to complement an x-ray fluorescence analysis. However, the reliability of such an analytical approach depends on good knowledge of

We present valence-to-core x-ray emission spectroscopy of Ti, TiO and TiO2 by means of a double crystal von Hamos spectrometer based on full-cylinder highly-annealed pyrolytic graphite mosaic crystals. We demonstrate that, using a double crystal conf

The redefinition of the kilogram will be based on Planck's constant, which can be calculated from Avogadro's constant, and hence by 'counting' the silicon atoms in a monocrystalline 28Si sphere weighing one kilogram. To reduce the influence of the su

Highly annealed pyrolytic graphite (HAPG) is an advanced type of pyrolytic graphite that, as a mosaic crystal, combines high integral reflectivity with a very low mosaicity of typically less than 0.1°. When used as dispersive X-ray optics, a high re

In this work the complete L-emission spectrum of gadolinium with respect to line energies, natural line widths, and relative transition probabilities was investigated using monochromatized synchrotron radiation. The measurements were realized in the

For the quantitative surface characterization of a monocrystalline silicon sphere PTB has constructed and taken into operation an analytical instrumentation, which combines X-ray fluorescence and X-ray photoelectron spectroscopy techniques. The main

The scaling down of critical dimensions for the manufacturing of nanoelectronics requires the continuous introduction of new materials. The results of the analysis of thin high-k films made from Al2O3 as reference samples were used at multiple labora
