By capturing the most energetic light in the sky, the spacecraft continues to teach us about the mysteries of the universe.

The foils, each made from a single chemical element, are used to calibrate X-ray equipment at SLAC’s SSRL synchrotron, and were donated by long-time...

In the decade since LCLS produced its first light, it has pushed boundaries in countless areas of discovery.

Marking the beginning of the LCLS-II era, the first phase of the major upgrade comes online.

The Small Business Innovation Research Program brings government and private industry together to develop next-generation X-ray optics for LCLS-II.

It uses terahertz radiation to power a miniscule copper accelerator structure.

Edward Hohenstein, Emma McBride and Caterina Vernieri study what happens to molecules hit by light, recreate extreme states of matter like those inside stars...

To break, or not to break: An unprecedented atomic movie captures the moment when molecules decide how to respond to light.

Kumar’s work, carried out in part at SSRL, explains how memristors work – a new class of electronic devices with applications in next-generation information...

Scientists precisely control where single-atom catalysts sit on their support structures, and show how changing their position affects their reactivity.

The results should further our understanding of similar reactions with vital roles in chemistry, such as the production of vitamin D in our bodies.

The first complete chemical analysis of feathers from Archaeopteryx, a famous fossil linking dinosaurs and birds, reveals that the feathers were patterned—light in color...
