We demonstrate a stabilization system for temporal and spectral drifts of an OPCPA pump-probe laser at the FLASH soft-x-ray FEL-facility. We achieve drifts of 5.7fs rms and 3.2nm rms, respectively over two days [...]

X-ray Free-Electron Lasers rely on low-emittance photo-injectors driven by UV laser pulses. For optimum performance temporally shaped laser pulses are desired. [...]

This chapter describes how the structure of molten silicates under high pressures may be measured by synchrotron X-ray diffraction, using either large-volume presses or diamond-anvil cells, the latter combined with resistive-heating or laser-heating techniques. A brief summary of the data obtained so far is given, followed by a description of both energy-dispersive and angle-dispersive techniques, including challenges and how they may be overcome. [...]

The high brilliance of synchrotron radiation has allowed us to combine microscopy with X-ray analytical techniques such as X-ray fluorescence, absorption spectroscopy, and diffraction. in this way, elemental, chemical and structural information can be obtained locally and with high spatial resolution. [...]

Beamline P64 at PETRA III is dedicated to x-ray absorption spectroscopy experiments which require high flux, like quick extended x-ray absorption fine structure spectroscopy on the sub-second time scale, high-resolution resonant emission spectroscopy, and x-ray absorption fine-structure spectroscopy of highly diluted systems. The beamline is installed at the high-energy storage ring PETRA III. [...]

The Helmholtz-Zentrum Geesthacht, Germany, is operating the user experiments for microtomography at the beamlines P05 and P07 using synchrotron radiation produced in the storage ring PETRA III at DESY, Hamburg, Germany. In recent years the software pipeline and sample changing hardware for performing high throughput experiments were developed. [...]

n this work we present x-ray phase-contrast tomography of heart tissue from mouse, combining computed tomography (CT) scans with laboratory and synchrotron radiation. The work serves as a proof-of-concept that the cyto-architecture and in particular the myofibril orientation can be assessed in three dimensions (3D) by phase-contrast CT. [...]

The commissioning of the European XFEL is ongoing. To reduce unwanted longitudinal micro-bunching effects, a laser heater is implemented. [...]

Metal Organic Frameworks (MOFs) have been of increasing interest over the last few years. They are structures which consist of metal ions or clusters coordinated to organic ligands in order to form one-, two-, or three-dimensional networks that often exhibit high porosity, an asset that is commonly exploited in hydrogen storage, heterogeneous catalysis and photo-catalysis as well as gas separation.
