Two-dimensional visible synchrotron light interferometry for transverse beam-profile measurement at the SPring-8 storage ring

A two-dimensional visible synchrotron light interferometer which has been newly developed for beam-profile measurement at the SPring-8 storage ring is reported.

Measurement of the two-photon correlation of synchrotron radiation in the VUV region by a delay-time modulation technique

The bunching effect due to the chaotic nature of the synchrotron radiation in the VUV region has been observed by a new technique.

Non-existence of positive glitches in spectra using the YB₆₆ double-crystal monochromator of BL15XU at SPring-8

Experiments have been carried out which clarify that a YB₆₆ double-crystal monochromator is well suited for soft X-ray beamlines on third-generation light sources.

The performance of a cryogenically cooled monochromator for an in-vacuum undulator beamline

The performance of a liquid-nitrogen-cooled silicon crystal monochromator has been studied by both finite-element modeling and experiments. The calculated rocking-curve width versus heat load is in excellent agreement with experiment.

Electrochemical in situ reaction cell for X-ray scattering, diffraction and spectroscopy

A versatile electrochemical in situ reaction cell for long-term hard X-ray experiments on battery electrodes is described. Applications include the small-angle scattering, diffraction and absorption spectroscopy of lithium manganese oxide electrodes.

A liquid-He cryostat for structural and thermal disorder studies by X-ray absorption

Atmospheric pressure conversion electron yield X-ray absorption measurements at temperatures from 4.2 to 300 K provide information on the temperature dependence of structural and dynamic properties of embedded clusters and thin films. A new device capable of electron yield measurements in this temperature range has been installed on beamline D42 in LURE.

A furnace design for XANES spectroscopy of silicate melts under controlled oxygen fugacities and temperatures to 1773 K

A furnace has been designed for in situ XANES spectroscopy of silicate melts, allowing, for the first time, the direct identification of Cr²⁺ in an Fe-bearing basaltic melt.

A glass capillary cell for in situ powder X-ray diffraction of condensed volatile compounds. Solid HCFC-123a and HCFC-124

The hexagonal crystal structures of 1,2-dichlorotrifluoroethane (HCFC-123a) and 2-chloro-1,1,1,2-tetrafluoroethane (HCFC-124) have been studied at temperatures down to 60 K in a rotating glass capillary cell with a gas handling system.
