jDiffraction - The basics of neutron diffraction

(by Alain Filhol, Jean Polge de Combret, Nicolas Morey-Chaisemartin and Yannick Raoul)

jDiffraction is available in English, French and German. It is intended as a support for teaching the basics of neutron diffraction of which it demonstrates the following aspects:

  1. Laue diffraction (diffraction of a polychromatic beam by a single crystal)
    You can appreciate the relationship between the diffraction pattern and both the lattice symmetry and crystal orientation.
  2. Lattice planes
    You can sense the relationship between atom planes and the diffraction process. The interactivity makes it easy to demonstrate the link between single crystal diffraction and powder diffraction. This is especially true if a fixed-angle sample rotation is used (Press the shift key).
  3. Diffraction of a monochromatic beam by a single crystal
    This demonstrates the influence of the wavelength of the incoming beam on the diffraction process.
  4. Diffraction of a monochromatic beam by a crystallin powder
    This demonstrates how a powder diffraction pattern is produced and you can see the influence of the wavelength of the beam on the resulting pattern.
  5. Magnetic diffraction
