1 X-NANO X-ray Waveguiding in Nanochannels: Fabrication, Experimental Proof of Concept, and Analysis of X-ray Propagation The aim of this research project is to demonstrate experimentally X-ray waveguiding in nanochannels of various origins, such as carbon nanotubes and anodic porous alumina membranes, and to design new elements of X-ray optics for forming nanosized beams and beams of a large-aperture and small divergence.
