题 目：Development of 10 nm X‐ray Microscopy: X‐ray Nanofocusing Optics to Science Experiments
报告人：Yong S. Chu(Hard X-ray Nanoprobe Beamline Group Leader at National Synchrotron Light Source II, Brookhaven National Laboratory, USA)
The Hard X‐ray Nanoprobe (HXN) Beamline at NSLS‐II is under construction in order to achieve an initial spatial resolution goal of 10 nm for a wide range of science experiments. With significant resolution enhancement from the other competing Nanoprobes around the world, the HXN beamline is aiming at exploring new frontiers of x‐ray microscopy, virtually eliminating large resolution gap between electron and visible‐light microscopy. Substantial R&D and designing efforts have been made for fabricating high‐resolution multilayer Laue lenses (MLLs), designing a scanning x‐ray microscope with 1nm positioning/scanning stability, and constructing a beamline that takes full advantage of the NSLS‐II source brightness and ensures sufficient stability for microscopy experiments.
The presentation will primarily focus on the recent progress in fabricating large‐aperture MLLs, x‐ray characterization of MLLs and development of an MLL x‐ray microscope for science experiments.
