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.
SLAC Director Chi-Chang Kao, a noted X-ray scientist, became the laboratory’s fifth director in November 2012. Kao came to SLAC in 2010 to serve as associate laboratory director for the Stanford Synchrotron Radiation Lightsource.
The lab is organized into five scientific directorates, each of which plays an important role in advancing our mission.
In 1962, construction began on what was the longest and straightest structure in the world: the two-mile linear particle accelerator. Learn the story of SLAC, from its founding to today.
The name SLAC National Accelerator Laboratory pays homage to the legacy of the lab and its connection to Stanford University and the Department of Energy (DOE).
SLAC National Accelerator Laboratory ("SLAC") requires our partners and colleagues to use the SLAC logos, names, or trademarks (together, "SLAC logos") and follow guidelines available on this page when publicizing SLAC's work and activities. These SLAC logos are the primary graphic identifiers of the laboratory and are meant for official use only.
