Stanford-SLAC Team Uses X-ray Imaging to Observe Running Batteries in Real Time

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost.

X-ray Laser Probes Biomolecules to Individual Atoms

An international team led by the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory has proved how the world's most powerful X-ray laser can assist in cracking the structures of biomolecules, and in the processes helped to pioneer critical new investigative avenues in biology.

Shaken, Not Heated: the Ideal Recipe for Manipulating Magnetism

Scientists have found a way to distort the atomic arrangement and change the magnetic properties of an important class of electronic materials with ultra-short pulses of terahertz (mid-infrared) laser light without heating the material up. While the achievement is currently of purely scientific interest, the researchers say this new approach control could ultimately lead to extremely fast, low-energy, non-volatile computer memory chips or data-switching devices.

Fifth X-ray Instrument at LCLS Debuts, With a Bead on Disorderly Structures

After five night shifts of shooting pairs of X-ray pulses through soups of fine sand and gold, Aymeric Robert was tired but exhilarated. The first experiment with an instrument he helped bring into being – the X-ray Correlation Spectroscopy (XCS) instrument at SLAC’s Linac Coherent Light Source – had just ended, launching a new tool for understanding liquids, glasses and other less-than-orderly substances.

Shedding Light

In 1971, physicist Burton Richter of Stanford Linear Accelerator Center was building a new type of particle collider called a storage ring. The lab’s two-mile-long linear accelerator—housed in what was then the longest building in the world—would shoot electrons and their antimatter twins, called positrons, into the 80-meter-diameter Stanford Positron Electron Accelerating Ring, and SPEAR would set the beams of particles on a collision course. Richter and his colleagues stood by to examine the debris to see what discoveries came out.

Giant Virus, Tiny Protein Crystals Show X-ray Laser's Power and Potential

Two studies to be published February 3 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.
