A High-Energy Monochromatic Laue (MonoLaue) X-ray Diffuse Scattering Study of KMnF₃ using an Image Plate

The technique of high-energy monochromatic Laue X-ray scattering using image plates to record the diffraction patterns is presented. A tunable wiggler beamline is used as an X-ray source. It is shown that such experimental conditions present many advantages over conventional tube sources and photographic films. A study of diffuse scattering in the perovskite compound KMnF₃ is presented to illustrate this in a qualitative way.
