This Java applet is a Java port of the Mac OS X application Diffraction. It is intended as a support for teaching the basics of neutron diffraction.

jDiffraction is available in three languages: English, French and German.

It demonstrates the following aspects of neutron diffraction:

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.
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
