Crystallography lecture notes

This lecture introduces crystallography, including the history and generation of x-rays

(Note that refractive optics for x-rays are used at the APS, in contrast to what is mentioned in the lecture)

This lecture discusses what is a crystal, defines the concept of a unit cell and defines the seven classes of unit cells

In a specific material with a known lattice constant and crystal structure, this allows the calculation of angles and distances between planes and directions of interest

For convenience, crystallographers sometimes refer to families of planes or directions, which all have the same indices but use different origins
