Carpentier, C. Berthet-Colominas, M. Capitan, M.-L. Chesne, E. Fanchon, S. Lequien, D. Thiaudière, J. Vicat, P. Zielinski and H. Stuhrmann Synopsis: The feasibility and review of long wavelengths and the use of anomalous dispersion is given. The instrument ID1 at the ESRF is a most promising tool for soft X-ray diffraction studies using the MAD method in structural studies and DAFS for site-selective spectroscopy. Online May 2000

J. Synchrotron Rad. (2000). 7, 152-159  [ doi:10.1107/S0909049500002971 ] Anomalous X-ray scattering for determining the partial structural functions of binary liquids M. Saito and Y. Waseda Synopsis: The availability of intense white X-rays from synchrotron radiation sources has greatly improved both acquisition and quality of anomalous X-ray scattering measurements. A demonstration is given of the usefulness of the anomalous X-ray scattering method for determining three partial structural functions of liquid matter by some selected examples of molten salts such as CuBr and RbBr.

J. Synchrotron Rad. (2000). 7, 196-201  [ doi:10.1107/S0909049500002995 ] Phase imaging using highly coherent X-rays: radiography, tomography, diffraction topography J. Baruchel, P. Cloetens, J. Härtwig, W. Ludwig, L. Mancini, P. Pernot and M. Schlenker Synopsis: The modern synchrotron radiation sources deliver highly coherent X-ray beams, associated with the small angular size of the source. The use of these beams for X-ray imaging leads to very original results. This is illustrated with examples recorded at the long (145 m) beamline, mainly devoted to imaging, at the ESRF.
