The Advanced Photon Source
a U.S. Department of Energy Office of Science User Facility
THE ADVANCED PHOTON SOURCE UPGRADE IS IN PROGRESS
The Advanced Photon Source 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. The facility will be closed for operations during this time.
Visit the APS Upgrade webpage for information about the project’s progress and future science at the facility. We look forward to completing the project and welcoming our users back to the APS this year.

APS/User News
The upgrade of the Advanced Photon Source (APS), a U.S. Department of Energy Office of Science user facility, reached a major milestone in December 2023. The final modules of the newly upgraded electron storage ring at the heart of the APS have now been installed, a significant step toward the completion of the removal and installation phase of the project that began in April 2023.
