Advance registration is required to participate in the joint onsite users’ meeting of the Stanford Synchrotron Radiation Lightsource (SSRL) and the Linac Coherent Light Source (LCLS), to be held at the SLAC National Accelerator Laboratory in Menlo Park, CA on September 21-26, 2025.  Every year, thousands of scientists from universities, laboratories, and private companies around the world use our cutting-edge research facilities. Their discoveries benefit a wide range of fields, including materials and energy sciences, chemistry, biology, medicine, environmental science, engineering, astronomy, and physics. 

This annual meeting is a unique opportunity to gather together the light source community in a single scientific event that includes numerous presentations in the plenary, poster, and parallel sessions. Participants can learn about current/future facility capabilities and the latest user research and discuss science with colleagues from academia, research laboratories, and industry worldwide.

This year, we’re offering:

  • 30 Workshops on diverse topics in synchrotron and XFEL science 
  • 2 Plenary Sessions with award presentations, poster blitz, hear from our facility directors, and distinguished guest speakers
  • Poster Session & Reception - a great opportunity for networking, exchanging ideas, and discussing the latest research with colleagues and experts in the field
  • Sponsor and Exhibitor Sessions –  engage with our sponsors and exhibitors, learn about their cutting-edge equipment and technologies, and explore potential collaborations
  • Back by Popular Demand - Food Trucks offering a variety of cuisines each day during lunch, excluding Sunday
  • NEW Outreach Initiative - Student Discovery Pass*: details below

SLAC NATIONAL ACCELERATOR LABORATORY

As one of 17 Department of Energy national labs, SLAC pushes the frontiers of human knowledge and drives discoveries that benefit humankind. We invent the tools that make those discoveries possible and share them with scientists all over the world.

SSRL provides extremely bright X-rays for a wide range of experiments that probe matter down to the scale of atoms and molecules. These studies target advances in energy production, human health, environmental cleanup, nanotechnology, novel materials and information technology, among other areas.

LCLS produces ultrafast pulses of X-ray laser light a billion times brighter than any previous X-ray source, allowing researchers to freeze the motions of atoms and molecules and string those images together to make stop-motion movies.

As part of your participation in the SSRL/LCLS Users' Meeting, please be aware that your name, email address,
and affiliation may be shared with our event sponsors and exhibitors.
This information is used to provide you with relevant updates, offers, and event-related communications.

 

SLAC is operated by Stanford University for the U.S. Department of Energy’s Office of Science. 

The Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
