Examples of data acquired with an X-ray energy of 8.0 keV. (a) Extended diffraction pattern from dry rat tail tendon collagen. Six diffraction patterns at different detector positions, each of which was made of two patterns to fill the gap between detector modules, were combined. The exposure time was 60 s. SDD = 160 mm. The red arrow indicates the meridional reflection at d = 0.286 nm. (b) Circular-averaged intensity profile of (a). The red arrow indicates the same peak as in (a). (c) Extended diffraction pattern from polypropylene (FY4). The exposure time was 10 s. SDD = 300 mm. The green arrow at q = 0.40 nm−1 indicates the peak from a lamellar structure, while the red arrow at q = 9.99 nm−1 indicates a peak from the crystalline structure of polypropylene. (d) Circular-averaged scattering curve of (c). The two arrows indicate the lamellar peak (green) and the crystalline peak (red). |
