They used SLAC’s ultrafast X-ray laser to follow the impact of a single electron moving within a molecule during an entire chemical reaction.

X-rays unveil new molecular structure details that will help researchers design novel drug therapies to address antibiotic resistant bacteria.

With their ability to penetrate matter and resolve individual atoms, X-rays and electrons are among scientists’ most useful tools for determining the structure and behavior of molecules and materials.

After a major upgrade, SLAC's X-ray free-electron laser is 10,000 times brighter and thousands of times faster. Now, researchers are using LCLS to observe...

On April 20, 2023 we celebrated 50 years of transformative science at SSRL. This unique event acknowledged many individuals who have made SSRL such a vital and impactful facility through partnerships among SSRL users and staff that fuel our success.

Download a variety of fact sheets to learn more about SLAC, our programs and latest scientific discoveries. 

SSRL and LCLS scientists will help visiting research teams solve their experimental challenges, then apply what they’ve learned to help others work more efficiently.

G6PD deficiency affects about 400M people worldwide and can pose serious health risks. Uncovering the causes of the most severe cases could finally lead...

His work has led to new treatments for advanced lung cancer and a better understanding of dangerous parasites.

Our original 2-mile-long particle accelerator, built half a century ago for groundbreaking particle physics research, has been repurposed as the world’s first hard X-ray free-electron laser and a testbed for next-generation accelerator technologies.
