Upgraded Advanced Photon Source Sees First X-ray Light For Science

JUNE 18, 2024: 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.

A new era of science at the Advanced Photon Source (APS) is ready to begin. On June 17, 2024, the facility at the U.S. Department of Energy’s (DOE) Argonne National Laboratory delivered its first X-ray light beams to a scientific beamline as part of a comprehensive and complex upgrade.

The APS, a DOE Office of Science user facility, has been a leading destination for X-ray science for nearly 30 years. Scientists from a

round the world use its ultrabright X-ray beams to learn more about our universe and lay the groundwork for longer-lasting batteries, more efficient solar cells and tougher materials for roads and bridges, to name a few. For the past year, operations have been paused at the facility while the original storage ring, which generates the X-ray beams, was removed and a brand-new ring installed.

“With more powerful X-ray beams and greatly enhanced beamlines, we’ll strengthen U.S. leadership in photon sciences.” — Paul Kearns, Argonne laboratory director

After more than a month of commissioning the new storage ring, the APS team has begun the process of bringing each of the 71 experiment stations, called beamlines, around the ring into operation. The first scientific beamline to receive X-rays was 27-ID, home of the resonant inelastic X-ray scattering program at the APS. Scientists will be able to use 27-ID to study complex materials that may be used to power the devices of the future.
