The Advanced Photon Source (APS) is undergoing a comprehensive upgrade to replace its original electron storage ring with a new, state-of-the-art accelerator. This will increase the brightness of APS X-ray beams by up to 500 times, and new beamlines will be constructed to take advantage of these improved capabilities. Check the APS-U website for updates. https://www.aps.anl.gov/APS-Upgrade
