16-Sep-2015 Q&A: Biologist describes milestone in watching proteins boogie
Using an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory, researchers have for the first time directly seen myoglobin move within quadrillionths of a second after a bond breaks and the protein releases a gas molecule. The Linac Coherent Light Source X-ray laser is a DOE Office of Science User Facility, and its short, bright pulses were essential for observing these ultrafast, atomic-scale motions.
14-Sep-2015 Scientists use lasers to simulate shock effects of meteorite impact on silica
Scientists used high-power laser beams at the Department of Energy's SLAC National Accelerator Laboratory to simulate the shock effects of a meteorite impact in silica, one of the most abundant materials in the Earth's crust.

3-Sep-2015 Researchers see 'spin current' in motion for the first time
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have for the first time seen a spin current -- an inherent magnetic property common to all electrons -- as it travels across materials.

31-Aug-2015 Q&A: Researchers explain a strange high-intensity result at SLAC's X-ray laser
At extremely high intensities, X-rays stop behaving like the ones in your doctor's office and begin interacting with matter in very different ways. This 'nonlinear' X-ray behavior can only be seen at X-ray free-electron lasers. Recent experiments at the Department of Energy's SLAC National Accelerator Laboratory have revealed a new, unexpected twist in that behavior that may be one for the textbooks and could change the way these powerful lasers probe matter.
20-Aug-2015 X-ray duo's research helps launch human trial for treatment of arsenic poisoning
Graham George and Ingrid Pickering, a husband and wife X-ray research team, have worked for decades to understand how contaminants in water and soil are taken up by the body and affect human health. Much of that research has taken place at the Stanford Synchrotron Radiation Lightsource (SSRL), a DOE Office of Science User Facility at SLAC National Accelerator Laboratory, where both are former staff scientists.
12-Aug-2015 Microscopic rake doubles efficiency of low-cost solar cells
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have developed a manufacturing technique that could double the electricity output of inexpensive solar cells by using a microscopic rake when applying light-harvesting polymers.
7-Aug-2015 Unique SLAC technology to power X-ray laser in South Korea
Accelerator technology pioneered at the Department of Energy's SLAC National Accelerator Laboratory is on its way to powering X-ray science in South Korea: On Aug. 6, the lab shipped one of its unique radio-frequency amplifiers -- an XL4 klystron -- to Pohang Accelerator Laboratory, where it will become a key component for the optimal performance of a new X-ray free-electron laser under construction.
5-Aug-2015 SLAC builds one of the world's fastest 'electron cameras'
A new scientific instrument at the Department of Energy's SLAC National Accelerator Laboratory promises to capture some of nature's speediest processes. It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules that take place in less than a tenth of a trillionth of a second -- information that will benefit groundbreaking research in materials science, chemistry and biology.
6-Jul-2015 Scientists drive tiny shock waves through diamond
Researchers have used an X-ray laser to record, in detail never possible before, the microscopic motion and effects of shock waves rippling across diamond. The technique, developed at the Department of Energy's SLAC National Accelerator Laboratory, allows scientists to precisely explore the complex physics driving massive star explosions, which are critical for understanding fusion energy, and to improve scientific models used to study these phenomena.
19-Jun-2015 SLAC research resumes at upgraded Large Hadron Collider
Research with the Large Hadron Collider has officially resumed: The world's largest particle accelerator at CERN began on June 3 to collect data at a new record energy that could hold the key to new scientific discoveries. To keep up with the boost in performance, researchers at the Department of Energy's SLAC National Accelerator Laboratory have developed new technologies for ATLAS -- one of two experiments involved in the 2012 discovery of the Higgs boson.
8-Jun-2015 President Obama honors Claudio Pellegrini with Enrico Fermi Award
Claudio Pellegrini, a visiting scientist and consulting professor at the Department of Energy's SLAC National Accelerator Laboratory and distinguished professor emeritus at the University of California, Los Angeles, will receive the 2014 Enrico Fermi Award for his role in laying the scientific groundwork for the X-ray free-electron laser.
27-May-2015 Spiraling laser pulses could change the nature of graphene
A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.
20-May-2015 SLAC gears up for dark matter hunt with LUX-ZEPLIN
The US Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components. DOE's SLAC National Accelerator Laboratory, a key member of the LZ collaboration, is setting up a test stand for the detector prototype and a facility to purify liquid xenon, which will be the detector's 'eye' for dark matter.
12-May-2015 Construction of LSST clean room at SLAC completed

5-May-2015 Compact light source improves CT scans
A new study shows that the recently developed Compact Light Source -- a commercial X-ray source with roots in research and development efforts at the Department of Energy's SLAC National Accelerator Laboratory -- enables computer tomography scans that reveal more detail than routine scans performed at hospitals today. The new technology could soon be used in preclinical studies and help researchers better understand cancer and other diseases.
