Large-area phase-contrast X-ray imaging using a two-crystal X-ray interfero­meter

The development and successful operation of a large-area (25 × 20 mm) phase-contrast X-ray imaging system using a two-crystal X-ray interferometer is reported.

X-ray diffraction topography using a diffractometer with a bendable mono­chromator at a synchrotron radiation source

A versatile bendable monochromator double-crystal diffractometer was constructed, to investigate, using synchrotron radiation, single-crystal samples with high strain sensitivity and without any reduced image sizes. It is based on a local adaptation of Bragg angles between monochromator and sample.

Diffuse scattering from liquid solutions with white-beam undulator radiation for photoexcitation studies

The natural bandwidth of a single-line undulator is used to measure solution scattering and optimize flux requirements for laser-pump–X-ray-probe time-resolved excitation studies.

Time dependence of the polarization of short X-ray pulses after crystal reflection

The time dependence of the polarization of short X-ray pulses is simulated by Fourier transforms using the steady-state solutions from dynamical theory. The mixed states in particular show a very pronounced time dependence, as perpendicular and parallel polarization components have a different time response.

Interaction of atomic systems with X-ray free-electron lasers

Atomic applications for XFELs are presented that include strong field effects, multiple ionization and hollow-atom formation.

First steps towards time-resolved BioXAS at room temperature: state transitions of the manganese complex of oxygenic photosynthesis

First time-resolved X-ray absorption spectroscopy experiments to study oxidation state and structural changes of biological metal centers are reported. The future impact of time-resolved BioXAS is discussed.

X-ray diffractometer designed for industrial applications at SPring-8 BL24XU

An X-ray diffractometer has been designed for industrial applications and installed at SPring-8 BL24XU in Japan. The diffractometer has been used for the grazing-incidence X-ray diffraction measurement of ion-implanted chromium-coated samples and for the X-ray stress measurement of polished stainless steel using our proposed new method.

Nearly diffraction-limited line focusing of a hard-X-ray beam with an elliptically figured mirror

X-ray focusing with an elliptically figured mirror is investigated.
