On the feasibility of large-aperture Fresnel lenses for the microfocusing of hard X-rays

W. Jark, F. Pérennès and M. Matteucci

Synopsis: The limitations of the aperture of highly regular Fresnel X-rays lenses due to absorption, chromatic aberrations and the `thin lens' approximation are discussed. Experimental data for the refraction efficiency are interpreted.

Temperature-resolved in situ X-ray absorption spectroscopic study on the reduction of nanostructured Fe₂O₃ within the pore system of mesoporous carbon CMK-1

H. Huwe and M. Fröba

Synopsis: First results on the reduction of iron oxide nanoparticles within a mesoporous carbon CMK-1 host structure are given. The thermochemical behaviour was monitored by temperature-dependent in situ X-ray absorption spectroscopic measurements. In summary, one can say that the kinetics of the reduction steps Fe₂O₃ Fe₃O₄ Fe_1-xO Fe⁰ are mainly affected by the particle size, as well as the spatial and chemical environment.

Nearly perfect large-area quartz: 4 meV resolution for 10 keV photons over 10 cm²

J. P. Sutter, A. Q. R. Baron, D. Miwa, Y. Nishino, K. Tamasaku and T. Ishikawa

Synopsis: Bragg backscattering of 10 keV X-rays from large commercial quartz crystals has shown low defect concentrations and experimental energy widths of 4.0 meV. Quartz thus appears to be a useful X-ray optical material, particularly for meV-resolution energy analyzers of X-rays with energy 12 keV or less.

High-resolution powder diffraction study of purple membrane with a large Guinier-type camera

T. Oka, K. Miura, K. Inoue, T. Ueki and N. Yagi

Synopsis: X-ray diffraction patterns from a film of oriented purple membranes, which comprise two-dimensional crystals of bacteriorhodopsin trimers, were recorded with a 1 m-pathlength Guinier-type camera at SPring-8 BL40B2. Diffraction peaks were observed up to a resolution of 2.3 Å and a projected electron density map was calculated with intensities up to a spacing of 4.2 Å.
