The first cryomodule has arrived at SLAC. Linked together and chilled to nearly absolute zero, 37 of these segments will accelerate electrons to almost the speed of light and power an upgrade to the nation’s only X-ray free-electron laser facility.

Planning the next big science machine requires consideration of both the current landscape and the distant future.

Innovations at SLAC, including the world’s shortest X-ray flashes, ultra-high-speed pulse trains and smart computer controls, promise to take ultrafast X-ray science to a whole new level.

In experiments with the lab’s ultrafast "electron camera," laser light hitting a material is almost completely converted into nuclear vibrations, which are key to switching a material’s properties on and off for future electronics and other applications.

In October, SLAC installed the first of LCLS-II’s cryogenic “feed caps” and “end caps.”

He is recognized for his numerous contributions to the advancement of accelerator physics, community service and education.

Claudio Pellegrini, a distinguished professor emeritus of physics at UCLA and adjunct professor of photon science at the Department of Energy’s SLAC National Accelerator Laboratory, has been elected to the National Academy of Sciences in recognition of his “distinguished and...

Researchers at SLAC are already looking at the largely unexplored realm of attosecond science.

Accelerator physicist Agostino Marinelli discusses how SLAC's X-ray laser makes femtosecond light.

SLAC celebrates five days of ultrafast science.

Join us for five days of ultrafast science from April 17 to 21.

Sila Kiliccote, Jodi Verleger and Lydia Young demonstrate what it means to live SLAC’s values.
