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.

Alexander Zholents, a senior physicist at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and distinguished fellow in the Accelerator Systems division is one of the recipients of this year’s Dieter Möhl Award.

As the APS procurement manager, Kizer and her team work with vendors to purchase the pieces that will make the APS’ X-ray beams shine 500 times brighter following the upgrade.

As the radiological user facilities manager, Beth Heyeck and her team will be the main points of contact for safety measures as the upgraded APS starts its new life.

Work on the beamlines for the APS Upgrade is ramping up. One of the most visible recent projects has been the assembly of the Grand Tube at beamline 9-ID, which this video depicts. The Grand Tube is a 70-foot-long enclosure that will allow scientists to image extremely small materials in three dimensions.

Eric Rod, Jesse Smith, Maddury Somayazulu, Jonathan Lang, John Quintana, and Nenad Velisavljevic were recognized for their contributions to nuclear security.

Dennis M. Mills, deputy associate laboratory director (DALD) for science and deputy director of the APS, will retire Nov. 6, 2023.
