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. 

What is SLAC National Accelerator Laboratory? The numbers tell the tale.

One of the most urgent challenges of our time is discovering how to generate the energy and products we need sustainably – in a way that doesn’t compromise the well-being of future generations by depleting limited resources or accelerating climate...

In its infancy, the universe was awash in fundamental particles. Over billions of years, matter cooled and clumped into stars and galaxies, tied together by a cosmic web of dark matter.

Working at the forefront of particle physics, SLAC scientists use powerful particle accelerators to create and study nature’s fundamental building blocks and forces, build sensitive detectors to search for new particles and develop theories that explain and guide experiments.

Accelerators form the backbone of SLAC's national user facilities. They are complicated machines, with hundreds of thousands of components that all need to be designed, engineered, operated and maintained to achieve the highest energy acceleration and the highest quality particle...
