The APS prepares for its renewal

The facility’s ultrabright X-ray beams will turn off for a year to enable a comprehensive upgrade, one that will light the way to new breakthroughs

With the start of the construction period, the Advanced Photon Source is now only a year away from re-emerging as a world-leading X-ray light source. Its brighter beams will lead to new discoveries in energy storage, materials science, medicine and more.

Today, a year-long effort to renew the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Argonne National Laboratory, officially begins.

After years of planning and preparation, the team behind the APS Upgrade project will now spend the next 12 months removing the old electron storage ring at the heart of the facility, replacing it with a brand new, state-of-the-art storage ring and testing the new ring once it is in place. The team will also build seven new experiment stations, construct the needed infrastructure for two more and update nearly every existing experiment station around the APS ring.

This is an extensive project, representing an $815 million investment from DOE. When complete, the APS will re-emerge as a world leader in global hard X-ray synchrotron science, enabling unimaginable new discoveries. Science conducted at the APS will lead to longer-lasting, faster-charging batteries, more durable airplane engines and better treatments for infectious diseases, among many other discoveries.

“The APS Upgrade is not only an investment in the facility’s future, but in the next 25 years of advancements that will change the way we power our vehicles, harness renewable energy and learn more about the fundamental science that underpins our future technologies.” — Linda Horton, associate director of science for Basic Energy Sciences, U.S. Department of Energy.

“This is a significant day for Argonne,” said Argonne Director Paul Kearns. ​“The APS Upgrade will transform the future of science for America and the world. Once we safely complete construction, the APS will shed new light on how the brain works, develop materials to decarbonize our economy, refine quantum technologies that can power the internet of the future and answer many other questions in numerous other disciplines.”
