The 40-foot-long segment of the new superconducting accelerator arrived on January 19, 2018 after a cross-country trip from Fermilab.

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.

The late artist June Schwarcz found inspiration in some unusual wrapping paper her husband brought home from the lab.

A makeover of the historic Beam Switch Yard prepares the lab for the installation of the LCLS X-ray laser upgrade.

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.
