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.

LCLS Powers Chain Reaction of Light: A New Tool for X-ray Studies

Researchers have found a new way to probe molecules and atoms with an X-ray laser, setting off cascading bursts of light that reveal precise details of what is going on inside, which could allow scientists to see details of chemical reactions in a way not possible before.

Backstory: Marc Messerschmidt, Staff Scientist

Marc Messerschmidt, a staff scientist at the Coherent X-ray Imaging (CXI) experimental station at SLAC's Linac Coherent Light Source X-ray laser, describes his daily work, which is far from routine.
