Copper anode in a X-rays generator.

x-rays, electromagnetic radiation beyond the remote ultraviolet ray, cover a range wavelength around the tenth of nanometer. This distance is about the distance between atoms in the condensed matter. The diffraction of x-rays thus makes it possible to probe the matter, and to obtain information on the structure, the order and the composition of materials.
