SLAC at a glance

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

SLAC by the Numbers

Founded in 1962 with 200 employees
1,600 employees from 55 countries plus 470 postdocs and grad students.
Thousands of researchers from around the world use our cutting-edge facilities.
699 tons of equipment removed from SLAC linac to make way for LCLS‑II
4 Nobel Prizes awarded to 6 laureates for their research at SLAC
20 companies use our X‑ray facilities for research aimed at developing medicines and other products.
Our linear accelerator structure is 3,073.72 meters long …one of the longest modern buildings on Earth!
Electrons zip down the accelerator at 669,600,000 mph …that's 99.9999999% of the speed of light!
180 universities & research institutes make use of our resources.
426-acre campus in Menlo Park, CA
SLAC works with Stanford in 5 joint research centers
Our X‑ray laser zaps samples with light pulses lasting 10-15 seconds …that's millionths of a billionth of a second!
Our lab has gone by 3 names
We’re assembling a 3.2 gigapixel camera for the Legacy Survey of Space and Time that will shoot the equivalent of 800,000 8-megapixel digital camera images per night.
36,000,000 °F matter created at LCLS mimics extreme conditions in the hearts of stars and planets.
200+ pulsars discovered by the Fermi Gamma‑ray Space Telescope since its launch in 2008. SLAC managed construction of its main instrument, the Large Area Telescope.
1975 The Homebrew Computer Club began meeting in the SLAC auditorium. This Silicon Valley grassroots group helped spark the personal computing revolution.
SLAC’s 1st scientific discovery is 14 million years old A Neoparadoxia repenningi fossil was found during excavation for the linear accelerator in 1964. The marine mammal resembled a hippo.
SLACVM was the 1st website in North America, designed in 1991 to help physicists share their research results.
LCLS‑II's X‑ray laser beam will be 10,000x brighter & fire 8,000x faster than that of the current LCLS, boosting the pulse rate up to one million pulses per second.
LCLS‑II's X‑ray laser beam will operate at 2 kelvins …colder than outer space!
Accelerators could become 1000x shorter with future plasma acceleration techniques developed at FACET‑II.
