Accepted 18 August 2016

Creating flat-top X-ray beams by applying surface profiles of alternating curvature to deformable piezo bimorph mirrors

A piezo bimorph mirror is deformed into three distinct re-entrant surface modifications as well as being simply defocused. A re-entrant modification with seven segments (the maximum possible for this mirror) produces an expanded beam with less striation than a simply defocused beam.

Accepted 13 August 2016

Fabrication and testing of a newly designed slit system for depth resolved X-ray diffraction measurements

A newly designed system of slits for depth resolved X-ray powder diffraction is developed and tested at the National Synchrotron Light Source.

Accepted 10 August 2016

Determination of the packing fraction in photonic glass using synchrotron radiation nanotomography

Synchrotron radiation nanotomography has been used to quantify the packing fraction in a photonic glass sample.

Accepted 8 August 2016

Nuclear Incorporation of Iron during the Eukaryotic Cell Cycle

Scanning X-ray fluorescence microscopy has been used to probe the distribution of S, P and Fe within cell nuclei at the new ID16 beamline. Estimates of P, S and mass signals for the chromosomal matter agree with quantitative X-ray phase contrast projection microscopy images of the same samples, while fluorescence shows Fe incorporation.

Accepted 5 August 2016

X-ray powder diffraction at the XRD1 beamline at LNLS

X-ray powder diffraction at the upgraded and comissioned XRD1 beamline is reported. The beamline operates in the 5.5–14 keV range with a photon flux of 3.4 × 1010 photons s−1 at 8 keV.

Accepted 4 August 2016

Interaction of a relativistic dense electron beam with a laser wiggler in a vacuum: self-field effects on the electron orbits and free-electron laser gain

Accepted 4 August 2016

Brownian and advective dynamics in microflow studied by coherent X-ray scattering experiments

Combining microfluidics with coherent X-ray experiments enables the flow characterization of collodial suspensions in microflow of different geometries. Here, evaluation of the flow geometries, main flow directions, advective flow velocities and diffusive dynamics are presented.

Accepted 4 August 2016

A multi-MHz single-shot data acquisition scheme with high dynamic range: pump–probe X-ray experiments at synchrotrons

A time-resolved X-ray absorption spectroscopy setup has been developed and tested, comprising a synchronized MHz fiber amplifier laser system with a multi-MHz data acquisition scheme capable of detecting multi-photon events in a single X-ray photon pulse. This system permits recording time-resolved X-ray absorption spectra with quasi static signal quality.

Accepted 4 August 2016

Measuring the criticality of the `magic condition' for a beam-expanding monochromator

The effect of minor mismatch between the geometric and single-ray foci for a cylindrically bent Laue double-crystal monochromator is examined and found to be less detrimental than previously believed. Even without exact matching, the transverse coherence of the X-ray beam is not deteriorated by the system, enabling the phase-based imaging techniques critical to modern biomedical imaging experiments.

Accepted 15 June 2016
