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.

To explore the birth of the universe, the formation of stars and galaxies and the fundamental structure of space and time, SLAC researchers develop cutting-edge technologies for sensitive experiments located deep underground, on the surface and in space.

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...

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

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.
