Scientists working at LCLS have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and opening the door to a new range of scientific discovery. more...

Researchers working at LCLS have used the world’s most powerful X-ray laser to create and probe a 2-million-degree piece of matter in a controlled way for the first time. This feat, reported today in Nature, takes scientists a significant step forward in understanding the most extreme matter found in the hearts of stars and giant planets, and could help experiments aimed at recreating the nuclear fusion process that powers the sun. more...

An international research team headed by DESY scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, has recorded the shortest X-ray exposure of a protein crystal ever achieved. The incredible brief exposure time of 30 femtoseconds (0.000 000 000 000 03 seconds) opens up new possibilities for imaging molecular processes with X-rays. more...

In 2009, when biophysicist Ilme Schlichting and her colleagues applied to use the X-ray laser at SLAC’s Linac Coherent Light Source, they added a radical idea to their proposal: They would make all the data they collected on two viruses and a nanoparticle available to the public one year after the experiment ended. more...

Diamonds can add more than sparkle and style to X-ray experiments at the Linac Coherent Light Source. They are giving scientists a way to focus the LCLS's powerful X-rays to a much tinier, brighter point without destroying the very device that does the focusing. more...

The great thing about SLAC’s Linac Coherent Light Source is that it churns out incredible volumes of data about things no one has ever seen before, such as snapshots of individual viruses. more...

In the first 18 months of Linac Coherent Light Source operation, the electron beam that drives the X-ray laser has exceeded expectations—so much so that SLAC's accelerator operators can offer impressive flexibility in crafting the beam to suit experiments, often changing its performance in mere minutes. more...

The first set of user experiments with the Linac Coherent Light Source's newest instrument is under way, and about 40 researchers are working very long hours this week to decipher the structures of proteins involved in photosynthesis, parasitic disease and other important life processes. more...

Two studies published in Nature demonstrate how the unique capabilities of the world's first hard X-ray free-electron laser—the Linac Coherent Light Source, located at the Department of Energy's SLAC National Accelerator Laboratory—could revolutionize the study of life. more...

Barely two months after publication of the first LCLS results on hollow atoms, two papers published in Physical Review Letters unveil the first results for hollow molecules. These studies show that the unprecedented intensity of the LCLS beam can reveal detailed information about a molecule's structure and dynamics.
"The LCLS is proving its mettle as a machine for discovery in strong-field atomic and molecular physics," said Phil Bucksbaum. Nora Berrah agreed. "The LCLS is already uncovering ma more...

In early October, researchers from around the globe began traveling to SLAC to get an initial glimpse into how the X-ray laser interacts with atoms and molecules. The LCLS is unique, shining light that can resolve detail the size of atoms at ten billion times the brightness of any other manmade X-ray source. “No one has ever had access to this kind of light before," said LCLS Director Jo Stöhr. “The realization of the LCLS isn’t only a huge achievement for SLAC, but an achievement for the global more...
