A vacuum-compatible monochromatic beam-position monitor using PIN photodiodes is described, based on fluorescence generated by a thin metal foil placed in the full X-ray beam. The true beam centre-of-mass is measured with a position sensitivity of 1–2 µm.

Two bent-crystal monochromators for 100 keV and 300 keV X-rays have been developed at the wiggler beamline BL08W of SPring-8.

It is shown that a properly designed transversal groove machined into the surface of a single-crystal monochromator may concentrate the diffracted radiation meridionally. This arrangement should provide two-dimensional focusing of a diffracted synchrotron radiation beam.

The non-linear optical effect of parametric down conversion has been demonstrated in the X-ray regime by combination of energy analysis and time correlation of the pairs of photons produced.

The design and performance of the high-brilliance XAFS facility at BL10XU of SPring-8, aimed at rapid and sensitive measurement of X-ray absorption fine structure, is reported.

Thermal effects in extended X-ray absorption fine structure and X-ray photoelectron diffraction due to atomic vibration in cubic and quartic potentials are studied by use of Feynman's path-integral approach.

A conical slit for three-dimensional XRD mapping has been manufactured by wire-electrodischarge machining. An algorithm for alignment of the slit is established, and the potential of the technique is illustrated with an example of grain mapping in a 4.5 mm-thick Cu sample.
