After a year of installation and commissioning, the new electron storage ring at the heart of the Advanced Photon Source — powered by a world’s first injection technique — is ready for business.

It's been an eventful month here at the Advanced Photon Source (APS), as we get closer and closer to welcoming users and their experiments back to the facility. We have some great updates to share with you.

The new electron storage ring at the center of the Advanced Photon Source (APS) has achieved another milestone: electrons are now circulating at a beam current of 25 milliamps (mA). This milestone marks the point when beamlines can begin to be verified and commissioned.

Sajaev and his team are in the midst of commissioning the new electron storage ring at the heart of the Advanced Photon Source.

The upgraded Advanced Photon Source (APS), a U.S. Department of Energy Office of Science user facility located at Argonne National Laboratory, is now the world’s first synchrotron light source to use a multi-bunch swap-out method of replenishing the electron beam in its storage ring.

Almost exactly a year ago, we shut down the Advanced Photon Source (APS) to begin removing the original electron storage ring and installing the new one we were still in the process of building. In this past year, our team accomplished a remarkable amount.

Award recognizes beamline scientists for significant contributions to research or instrumentation at the Advanced Photon Source.

Today (April 20, 2024) the upgraded Advanced Photon Source (APS) took another important step forward, as the Accelerator Systems Division (ASD) team reported the first stored beam in the new storage ring.

Electrons have made their way around the new Advanced Photon Source (APS) storage ring for the first time, a major milestone in the process of bringing the newly upgraded APS into operation.

The Advanced Photon Source (APS) Upgrade project officially moved into a new phase today, as commissioning of the new storage ring began.

Award recognizes important scientific or technical accomplishments at (or beneficial to) the Advanced Photon Source.

Mechanical engineering specialist Grace Avellar oversees the successful installation and tracking of components for beamlines as part of the APS Upgrade.

For the first time since April 2023, electrons are circulating in the booster accelerator, bringing the Advanced Photon Source (APS) one step closer to fully returning to life.

The Facilities Integrating Collaborations for User Science (FICUS) program has opened its annual call for biological and environmental research proposals for fiscal year 2025. The deadline for Letter of Intent submission is March 7.

We are bringing back the traditional Users Meeting experience this year for an exciting week of user science presentations, workshops, facility updates, and more, all taking place IN PERSON at Argonne! This year is your opportunity to network and reconnect. Register today! The registration deadline is April 22 at 4:59 p.m. CT.

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.

HPCAT, the High-Pressure Collaborative Access Team, at the U.S. Department of Energy’s Advanced Photon Source (APS), recently celebrated its 20-year anniversary, commemorated during a workshop.
