After a yearlong installation, light has returned to the world-leading Advanced Photon Source. Users across a gamut of disciplines, from materials to planetary science, are getting their research proposals ready.

Several members of the Advanced Photon Source (APS) team were among the dozens of Argonne employees honored this year with an Argonne Board of Governors Award. The annual awards recognize distinguished employee performance, outstanding service to the laboratory and excellence in education, safety and diversity, equity, inclusion and accessibility (DEIA).

Gilberto Fabbris, a physicist in the X-ray Science Division, has been named a recipient of an Early Career Research Program award from the U.S. Department of Energy (DOE) Office of Science for 2024.

The new measurement confirms the world-leading status of the APS as it returns to operation following a shutdown for a comprehensive upgrade.

The ultimate power source that powers the stars themselves, nuclear fusion is capable of producing clean, essentially unlimited energy and solving humankind's needs into the far distant future if the technological challenges to its realization can be met.

Three GM/CA users have been awarded the inaugural prize for their outstanding research contributions to the field of immunology.

Chengjun Sun, Mikhail Solovyev and Shelly Kelly of the X-ray Science Division won a prestigious R&D 100 award for their AXES project, a complete advanced X-ray emission spectroscopy (XES) solution featuring a new spectrometer with the unprecedented ability to probe seven different elements simultaneously. AXES uses artificial intelligence to perform data analyses in real time with minimal human intervention.

Elected officials and leaders from the Department of Energy join us for an outdoor ceremony to dedicate the upgraded APS.

The Users’ Executive Committee’s new members and leadership were nominated and elected by the APS user community and will serve for three-year terms.

On July 17, 2024, elected officials and Department of Energy leaders joined Argonne to dedicate the upgraded Advanced Photon Source (APS).

Elected officials, Department of Energy leaders and other luminaries joined Argonne today to dedicate the upgraded APS.

Technical Facilities and Systems Specialist Laura Boon is applying the skills from her experience working on the Advanced Photon Source Upgrade across Argonne’s campus.

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.
