SLAC Physicist Receives Free-electron Laser Award

Dao Xiang, a SLAC accelerator physicist, has received an international award for his work on a technique for tuning an electron beam with a laser to produce X-ray pulses with more uniform and predictable properties.

Ribosome Research Takes Shape at SLAC

In a new state-of-the-art lab at SLAC National Accelerator Laboratory, components of ribosomes – tiny biological machines that make new proteins and play a vital role in gene expression and antibiotic treatments – form crystals in a liquid solution.

Signs at the lab's entryway warn of the potential for contamination – these delicate samples can be damaged by human touch, a sneeze or a dust particle.

Annual SSRL Award Honors Former Stanford Grad Student

Jonathan Rivnay, a former Stanford graduate student who is now a postdoctoral fellow at the Center of Microelectronics in Provence, France, will receive this year's William E. and Diane M. Spicer Young Investigator Award in recognition of his synchrotron studies of organic semiconductors.

Rapid Beam-switching Allows SLAC X-ray Laser to Multitask

A high-energy SLAC laser that creates shock waves and superhot plasmas needs to cool for about 10 minutes between shots. In the meantime, the rapid-fire pulses produced by SLAC's Linac Coherent Light Source X-ray laser, which probes the extreme states of matter produced by this initial laser shot, are unused.

A New Tool to Split X-ray Laser Pulses

A new tool at SLAC's Linac Coherent Light Source splits individual X-ray laser pulses into two pulses that can hit a target one right after another with precisely controlled timing, allowing scientists to trigger and measure specific ultrafast changes in atoms and molecules.
