Abstract
Section titled āAbstractāWe demonstrate parabolic single-crystal diamond compound refractive lenses designed for coherent x-ray imaging resilient to extreme thermal and radiation loading expected from next generation light sources. To ensure the preservation of coherence and resilience, the lenses are manufactured from the highest-quality single-crystalline synthetic diamond material grown by a high-pressure high-temperature technique. Picosecond laser milling is applied to machine lenses to parabolic shapes with a ā1 Ī¼m precision and surface roughness. A compound refractive lens comprised of six lenses with a radius of curvature R=200 Ī¼m at the vertex of the parabola and a geometrical aperture A=900 Ī¼m focuses 10 keV x-ray photons from an undulator source at the Advanced Photon Source facility to a focal spot size of ā20Ć90 Ī¼m2 with a gain factor of ā50ā100.
