摘要

The upgraded Advanced Photon Source (APS) will be optimized to produce hard X-rays with a high degree of spatial coherence, and will exceed the capabilities of today's synchrotrons by two to three orders of magnitude in brightness and coherent flux in the hard X-ray range [1]. It will particularly benefit techniques such as advanced X-ray nanoprobes for nanoscale imaging, nanospectroscopy, and nanodiffraction. It will also benefit coherent diffractive imaging and ptychography with spatial resolution approaching atomic length scales and permitting timeresolved studies [2]. Meanwhile, many beamlines will be upgraded to take advantage of the smaller emittance for nanofocusing and nanoscale imaging. All of these methodologies will need novel precision X-ray instruments, including nanopositioning stages, to make full use of the new diffraction-limited storage ring capabilities.
