(a) A schematic description of the instrumental setup. The X-ray detector is placed at either the short-distance (108 mm, WAXS) or the long-distance (7092 mm, SAXS) position. (b) A typical two-dimensional WAXS frame. (c) The hydroxyapatite unit cell. (d) A typical two-dimensional SAXS frame showing meridional and equatorial reflections. (e) and (f) The relative orientation of the collagen fibrils and the scattered (meridional and equatorial) intensity peaks (Wilkinson & Hukins, 1999) with the corresponding SAXS experimental patterns. The detector frame in (d) has been rotated to match the orientation of the sketches in (e) and (f). |
