Automation of the EMBL Hamburg protein crystallography beamline BW7B

The automation of the EMBL Hamburg wiggler beamline BW7B for protein crystallography is described. The beamline features an automated end-station, a robotic sample changer, semi-automated sample centering based on UV fluorescence and new control software including intuitive graphical user interfaces.

An X-ray BBB Michelson interferometer

An X-ray BBB interferometer has shown intensity oscillations when its front mirror was displaced by a piezoelectric disc translator. These were caused by the change in the length of the front path while that of the back path stayed constant.

Prediction of the transmission through thin-film waveguides for X-ray microscopy

X-ray waveguides can routinely compress incident X-ray beams to submicrometre dimensions. State-of-the-art one- and two-dimensional waveguides are found to provide transmission efficiencies of 50% for spatially coherent incident radiation in each dimension.

A device for selecting and rejecting X-ray harmonics in synchrotron radiation beams

A novel device for selecting and rejecting a specific undulator harmonic in synchrotron radiation experiments is described and tested. The device can be used to effectively extend the working energy range of monochromators.

The BioCAT undulator beamline 18ID: a facility for biological non-crystalline diffraction and X-ray absorption spectroscopy at the Advanced Photon Source

The undulator beamline of the Biophysics Collaborative Access Team (BioCAT), a national user facility designed and dedicated to the study of partially ordered and disordered biological materials, is described and examples of its capabilities are presented.

Collection of reciprocal space maps using imaging plates at the Australian National Beamline Facility at the Photon Factory

Imaging plates have been used in Weissenberg flat-cone geometry to rapidly collect reciprocal space maps of InGaN/GaN/AlN multilayers. The maps obtained with imaging plates were compared with triple-axis diffractometry results.

Fischer-Tropsch synthesis: study of the promotion of Pt on the reduction property of Co/Al₂O₃ catalysts by in situ EXAFS of Co K and Pt L_III edges and XPS

The promotion of Pt on Co/Al₂O₃ catalysts for Fischer-Tropsch synthesis was studied by EXAFS and XANES at both the Co K edge and Pt L_III edge. Direct contact of Pt with the active Co clusters was established by EXAFS, while XANES revealed that Pt assists in promoting the reduction of Co clusters interacting with Al₂O₃, thereby increasing the number of surface Co metal active sites.

XMCD under pressure at the Fe K edge on the energy-dispersive beamline of the ESRF

The feasibility of X-ray absorption spectroscopy and X-ray magnetic circular dichroism at high pressure at the Fe K edge on the ID24 energy-dispersive beamline of the ESRF is demonstrated.

Source identification of PM₁₀, collected at a heavy-traffic roadside, by analyzing individual particles using synchrotron radiation

Micro-SXRF was used successfully to study the origins of individual aerosol particles. A method based on the analysis of individual aerosol particles combined with a pattern recognition technique was developed to identify the sources of PM₁₀.

Diffractive imaging of nonperiodic materials with future coherent X-ray sources

Experimental opportunities in coherent diffraction imaging with an iterative phasing algorithm are discussed based on the coherent properties of the proposed energy-recovery linac source.

Reciprocal correlation between fringe contrast and amplitude of an anomalous oscillation of X-ray Pendellösung fringes

The amplitude of an anomalous oscillation of X-ray Pendellösung interference fringes is compared with the distribution of fringe contrast on a quantitative basis in order to clarify that the fringe-oscillation amplitude is in good correlation with the reciprocal of fringe contrast.
