Secretary of Energy Rick Perry Visits SLAC, Tours Site of X-ray Laser Upgrade

The DOE’s top official met with SLAC staff and toured the Linac Coherent Light Source X-ray laser, where a superconducting upgrade is underway.

Social Media: Highlights from Six Months of LCLS Experiments

Here's a glimpse of what we've been up to during the last experimental run – from June to November 2017 – at the Linac Coherent Light Source.

Scientists See Molecules ‘Breathe’ in Remarkable Detail

The research team was able to watch energy from light flow through atomic ripples in a molecule. Such insights may provide new ways to develop a class of materials that improve efficiency and reduce the size of applications like solar cells and memory storage devices.

Scientists Get First Direct Look at How Electrons ‘Dance’ with Vibrating Atoms

Extraordinarily precise measurements -- within millionths of a billionth of a second and a billionth of a hair's breadth -- show this ‘electron-phonon coupling’ can be far stronger than predicted, and could potentially play a role in unconventional superconductivity.

SLAC Experiment is First to Decipher Atomic Structure of an Intact Virus with an X-ray Laser

The method dramatically reduces the amount of virus material required and allows scientists to get results several times faster.

'Schroedinger's Cat' Molecules Give Rise to Exquisitely Detailed Movies

Just as Schroedinger's Cat is both alive and dead, an atom or molecule can be in two different states at once. Now scientists have exploited this behavior to make X-ray movies of atomic motion with much more detail than ever before.

Winning Photos from the 2015 SLAC Physics Photowalk

The SLAC Photowalk took a group of 17 photographers, both amateur and professional, behind the scenes to photograph SLAC's world-class science facilities, including the Linac Coherent Light Source (LCLS) X-ray laser and the Stanford Synchrotron Radiation Lightsource (SSRL).
