The thermal deformation of these x-ray optics due to heat loads of the x-ray beam has been previously shown to be able to be partially mitigated by adding a groove or notch on the side of the optic and below the optical surface. This notch acts as a thermal break which allows for anti-clastic bending and the notch geometry can be optimized for various heat loads. By optimizing the notch height, depth, and distance from the optical surface the thermal deformation on the optic can be minimized. The High Heat Load Mirror systems of the Advance Photon Source (APS) feature beamlines rely on this notch geometry to be able to take full advantage of the new source of the APS Upgrade.
