The high-energy upgrade will keep the U.S. at the forefront of X-ray science and technology, allowing researchers to advance fields such as sustainability, human health and quantum information.

With up to a million X-ray flashes per second, 8,000 times more than its predecessor, it transforms the ability of scientists to explore atomic-scale, ultrafast phenomena that are key to a broad range of applications, from quantum materials to clean...

X-ray laser experiments show that intense light distorts the structure of a thermoelectric material in a unique way, opening a new avenue for controlling the properties of materials.

These fleeting disruptions, seen for the first time in lead hybrid perovskites, may help explain why these materials are exceptionally good at turning sunlight into electrical current in solar cells.

The results, which show that ultrafast atomic motions are the first step in forming a magnetic state, could lead to faster and more efficient data storage devices.

Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into...

Experiments at SLAC’s X-ray laser reveal in atomic detail how two distinct liquid phases in these materials enable fast switching between glassy and crystalline states that represent 0s and 1s in memory devices.

In the decade since LCLS produced its first light, it has pushed boundaries in countless areas of discovery.

X-ray laser snapshots give scientists a new tool for probing trillionths-of-a-second atomic motions in 2-D materials
