Highlighted illustration

Cover illustration: Three-dimensional shaded surface plot for trigonal tellurium in a study of the local structure of amorphous tellurium, which shows the correlation between the coordination number and the Debye-Waller factor in EXAFS analysis (see Ikemoto and Miyanaga, pages 409-412). The colour and surface height are proportional to the R-factor.

The performance of a cryogenically cooled double-crystal silicon monochromator was studied under high-heat-load conditions with total absorbed powers and power densities ranging from 8 to 780 W and from 8 to 240 W mm−2, respectively. When the temperature of the first crystal is maintained close to the temperature of zero thermal expansion of silicon, the monochromator shows nearly ideal performance with a thermal slope error of 0.6 µrad.

The design and performance of a new soft X-ray beamline BL07LSU at SPring-8 are described. The combination of a novel segmented cross undulator and beamline monochromator has achieved high energy resolution (EE > 10000) and high photon flux [>1012 photons s−1 (0.01% bandwidth)−1] in the photon energy range 250–2000 eV with fully controllable polarization.

Dual loop active feedback stabilization of the position and monochromatic flux of the beam at the output of a double-crystal monochromator is described. The efficacy of the proposed stabilization system is demonstrated in EXAFS spectroscopy measurements on inhomogeneous diluted Ti-containing samples.

The local structure of amorphous tellurium was investigated by EXAFS. The primary chain structure remains intact, whereas the secondary structure is disrupted. The decrease in the inter-chain interaction strengthens the intra-chain interaction.

The X-ray mass attenuation coefficients of silver were measured in the energy range 5–20 keV with an accuracy of 0.01–0.2% on a relative scale down to 5.3 keV, and of 0.09–1.22% on an absolute scale to 5.0 keV, confirming that with careful choice of foil thickness and careful correction for systematics the X-ray attenuation of high-Z elements can be measured with high accuracy even at low X-ray energies.

The feasibility of propagation-based X-ray phase-contrast imaging of small animal lungs has been investigated at the Imaging and Medical beamline (IMBL) of the Australian Synchrotron, including computed tomography and X-ray velocimetry. Excellent contrast of the lung phantoms indicates that live animal lung imaging can readily be achieved at the IMBL.
