Abstract: Eight potential monochromator crystal designs were subjected to a combination of three different beam powers on two different footprints. The temperature and thermal deformation were determined for each. It was found that thermal deformation of the lattice is negligible compared to the surface curvature, and that while the thinnest crystal wafer showed the smallest temperature increase, crystals cooled from the bottom alone demonstrated a far more uniform thermal deformation and a larger radius of curvature.
