Dr. Stephen Kevan will present his topic in person.

Abstract: I will describe ongoing accelerator upgrades that are increasing the x-ray brightness of synchrotron light sources by a factor of 100-1000, and elaborate examples of new science opportunities enabled by this ultrahigh brightness. The small size of the source and collimation of the photon beams from undulators will produce nearly diffraction-limited soft x-ray beams, allowing to large improvements in x-ray microscopy, x-ray photon correlation spectroscopy, and experiments with shaped x-ray wavefronts.  I will illustrate how the improved spectral, spatial, and temporal sensitivity of these beams will provide new probes of functioning mesoscale structures, thereby bridging the nanoscale and mesoscale in various contexts.
