Progress in X-ray scattering

In principal, the scientic questions addressed can be investigated by X-ray scattering. This fact has been well-known for decades. Therefore great, engineering efforts have been undertaken for a long time to optimize the components of X-ray setups. 

Parts with fiber symmetry, like fibers, rods or tubes, are not only of practical interest because they are ubiquitous in everyday life. Moreover, they appear paxticularly suited for investigation by means of scattering methods. As the part is rotated about its axis, the 2D scattering pattern does not change. Thus, there is no advantage to take patterns at different rotation angles as it would be for oriented materials with less symmetry. 

The recorded 2D scattering pattern of a fiber is oriented and contains all the accessible information on the structure of the sample.
