Marking the beginning of the LCLS-II era, the first phase of the major upgrade comes online.

A proposed device could expand the reach of X-ray lasers, opening new experimental avenues in biology, chemistry, materials science and physics.

The prestigious awards provide at least $2.5 million over five years in support of their work in understanding photochemical reactions and improving accelerator beams.

It could offer insights into the evolution of planetary systems and guide scientists hoping to harness nuclear fusion as a new source of energy.

Revealing both sides of the story in a single experiment has been a grand scientific challenge.

Understanding nature’s process could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.

Learning how liquid silicates behave at these extreme temperatures and pressures has been a longstanding challenge in the geosciences.

The advance opens a path toward a new generation of logic and memory devices that could be 10,000 times faster than today's.

Siegfried Glenzer's team and collaborators from Tel Aviv University are working on a method that could make proton accelerators 100 times smaller without giving up any of their power.

Light-driven reactions are at the heart of human vision, photosynthesis and solar power generation. Seeing the very first step opens the door to observing chemical bonds forming and breaking.

It combines human knowledge and expertise with the speed and efficiency of “smart” computer algorithms.

New research shows that when a bunch of electrons zooms through the middle of a ring-shaped laser beam, the bunch can wind up with higher quality and generate a brighter X-ray beam.
