C 4 - Multilayer zone plates and Laue lenses for x-ray microscopy

The main goal of the proposed project is the design, fabrication, and application of multilayer zone plates (MZPs) for two-dimensional hard x-ray imaging with resolutions of 10nm and below. Using MZPs, we already have demonstrated sub-5nm point focusing of hard x-rays, and preliminary results show the possibility of high-resolution imaging (collaboration of C01 and C04).
Methods developed in the projects C01, C04 and C05 (which in the first period concentrated on "optimized focusing of hard x-rays by nanostructures") will be
joined in the new project C12 to further advance from nano-focusing to high resolution imaging using hard x-rays.
