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.

Communication is Key, Says Theorist Gennady Stupakov

One common stereotype of a theoretical physicist is the solitary scientist, scribbling away in his or her office and only emerging when there’s a "Eureka!" in the offing. SLAC accelerator physicist Gennady Stupakov would beg to differ.

Spencer Gessner Receives 2014 Siemann Fellowship

Stanford graduate student Spencer Gessner has received a Siemann fellowship to help him continue his research into cutting-edge accelerator physics at SLAC's Facility for Advanced Accelerator Experimental Tests.

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.

Researchers Demonstrate 'Accelerator on a Chip'

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.

SLAC Scientists Create Twisted Light

Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light in shorter pulses, higher intensities and a much wider range of wavelengths, including X-rays, than is currently possible.

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.
