Five Years of Illumination: SLAC's Linac Coherent Light Source

Five years ago, the brightest source of X-rays on the planet lit up at SLAC. The Linac Coherent Light Source (LCLS) X-ray laser's scientific and technical progress since its momentous "first light" have been no less luminous, say those who have played a role in its success.

Data-mining for Crystal 'Gold' at SLAC's X-ray Laser

A new tool for analyzing mountains of data from SLAC’s Linac Coherent Lightsource (LCLS) X-ray laser can produce high-quality images of important proteins using fewer samples. Scientists hope to use it to reveal the structures and functions of proteins that have proven elusive, as well as mine data from past experiments for new information

A New Way to Tune X-ray Laser Pulses

A new system at SLAC National Accelerator Laboratory's X-ray laser narrows a rainbow spectrum of X-ray colors to a more intense band of light, creating a much more powerful way to view fine details in samples at the scale of atoms and molecules.

LAMP: A New Tool Turns On at SLAC's X-ray Laser

A 2-ton instrument the size of a compact car, now available at SLAC's X-ray laser, makes it possible to capture more detailed images of atoms, molecules, nanoscale features of solids, and individual particles such as viruses and airborne soot.

Scientists Line Up Unruly Gas Molecules for X-rays

It's hard to study individual molecules in a gas because they tumble around chaotically and never sit still. Researchers at SLAC overcame this challenge by using a laser to point them in the same general direction, like compass needles responding to a magnet, so they could be more easily studied with an X-ray laser.

X-ray Laser Maps Important Drug Target

Researchers have used one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than possible before.
