Figure 8
A classic MX experiment. Many of the components are described in the main text of the article. Note in particular that two possible experimental setups are superimposed: one with the detector close in and the second with it pushed back. Owing to the Bragg reflections expanding from an effective source position many metres upstream of the crystal, the spot shape and intensity are not very different in the two experiments, whereas the background scattering, which arises largely from scattering from disordered crystal components, material around the crystal and air scattering from the direct beam between the guard aperture and the backstop, falls off as the square of the distance from that point to the detector and is therefore dramatically reduced at longer crystal-to-detector distances.
