This index page links to descriptions of the ILL Diffraction Group neutron
instruments and some of the experiments carried out using them. It points to
various crystal databanks and other sites of interest to crystallographers, and
in particular the
EPSRC-ILL meeting on Millennium Projects at ILL Grenoble, 26-28 May 2005.

Visualise 3D diffraction patterns with VRML
- Surf3d (B. Nunes) and a simple
numor-reading program, make 3D visualization of powder diffraction scans
easy with VRML. First, try this D1B example data from a healed bone
fracture (G. Bacon) on an SGI or other computer. The 'terrain map' shows
neutron intensity as a function of scattering angle and distance along the
bone. The sharp dip in intensity of the strongest line, and corresponding
change in other lines, is due to the reduced preferred orientation of
apatite crystals at the healed break. Since the strength of bones is
related to the orientation of these crystallites, the new growth is
inherently weaker, but this is compensated by its greater volume.
