12-Aug-2016 Fermi researchers explore new ways of searching for dark matter
Researchers working with more than six years of data from NASA's Fermi Gamma-ray Space Telescope have used novel approaches to search for cosmic signals that could reveal what mysterious dark matter is made of. The scientists looked for hypothetical axion particles, studied the gamma-ray emissions from a large satellite galaxy of our Milky Way and analyzed the faint glow of gamma rays that covers the entire sky.
9-Aug-2016 DOE approves construction of 3-D galaxy-mapping project 'DESI'
A 3-D sky-mapping project that will measure the light of 35 million cosmic objects has received formal approval from the Department of Energy to move forward with construction. Installation of the project, called Dark Energy Spectroscopic Instrument (DESI), is set to begin next year at the Mayall 4-meter telescope at Kitt Peak National Observatory near Tucson, Arizona, with observations starting up in January 2019.
2-Aug-2016 Physicist trio amplifies SLAC research on mysterious forms of matter
All material things appear to be made of elementary particles that are held together by fundamental forces. But what are their exact properties? Questions with cosmic implications like this drive many of the scientific efforts at the Department of Energy's SLAC National Accelerator Laboratory. Three distinguished particle physicists have joined the lab over the past months to pursue research on two particularly mysterious forms of matter: neutrinos and dark matter.
29-Jul-2016 Stanford, SLAC play key role in new DOE battery consortium
A newly formed Battery500 consortium, including researchers from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, will receive up to $10 million each year for the next five years to develop a new battery technology that could make electric vehicles go two to three times farther and make them less expensive.
11-Jul-2016 Siemann Graduate Fellowships help advance accelerator research
Four graduate students working on innovative accelerator technologies at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have been awarded Robert H. Siemann Graduate Fellowships in Physics. Established in memory of long-time SLAC accelerator physicist and Stanford faculty member Robert Siemann, the fellowship provides funding to outstanding graduate students doing accelerator research at the lab.
3-Jul-2016 Greene scholars explore science and engineering at SLAC
Jaden Morgan, a 13-year-old rising freshman who will attend Bellarmine College Preparatory in San Jose this fall, had heard about SLAC's legendary 2-mile-long accelerator but had never been to the lab. This summer he had the chance to see the Department of Energy's SLAC National Accelerator Laboratory facilities up close and hear how they are used to explore the world at the level of atoms and molecules.
22-Jun-2016 Learning about the future from the distant past
Our universe came to life nearly 14 billion years ago in the Big Bang -- a tremendously energetic fireball from which the cosmos has been expanding ever since. Today, space is filled with hundreds of billions of galaxies, including our solar system's own galactic home, the Milky Way. But how exactly did the infant universe develop into its current state, and what does it tell us about our future?
14-Jun-2016 X-ray experiments show Hewlett Packard team how memristors work
In experiments at two Department of Energy national labs -- SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory -- scientists at Hewlett Packard Enterprise (HPE) have experimentally confirmed critical aspects of how a new type of microelectronic device, the memristor, works at an atomic scale.
6-Jun-2016 Echo Technique Developed at SLAC Could Make X-ray Lasers More Stable
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Shanghai Jiao Tong University in China have developed a method that could open up new scientific avenues by making the light from powerful X-ray lasers much more stable and its color more pure.
6-Jun-2016 Scientists Use a Frozen Gas to Boost Laser Light to New Extremes
Researchers at the Department of Energy's SLAC National Accelerator Laboratory, Stanford University and Louisiana State University have achieved an even more dramatic HHG shift by shining an infrared laser through argon gas that's been frozen into a thin, fragile solid whose atoms barely cling to each other.
2-Jun-2016 A plasma tube to bring particles up to speed at SLAC
A team led by scientists from the University of California, Los Angeles and the Department of Energy's SLAC National Accelerator Laboratory has reached another milestone in developing a promising technology for accelerating particles to high energies in short distances: They created a tiny tube of hot, ionized gas, or plasma, in which the particles remain tightly focused as they fly through it.
1-Jun-2016 Prototype of LUX-ZEPLIN dark matter detector tested at SLAC
Prototyping of a new, ultrasensitive 'eye' for dark matter is making rapid progress at the Department of Energy's SLAC National Accelerator Laboratory: Researchers and engineers have installed a small-scale version of the future LUX-ZEPLIN (LZ) detector to test, develop and troubleshoot various aspects of its technology.
Alex Aiken, director of the new Computer Science Division at the Department of Energy's SLAC National Accelerator Laboratory, has been thinking a great deal about the coming challenges of exascale computing, defined as a billion billion calculations per second. That's a thousand times faster than any computer today. Reaching this milestone is such a big challenge that it's expected to take until the mid-2020s and require entirely new approaches to programming, data management and analysis, and numerous other aspects of computing.
23-May-2016 Caught on camera: First movies of droplets getting blown up by X-ray laser
Researchers have made the first microscopic movies of liquids getting vaporized by the world's brightest X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. The new data could lead to better and novel experiments at X-ray lasers, whose extremely bright, fast flashes of light take atomic-level snapshots of some of nature's speediest processes.
12-May-2016 Extracting miniature diamonds from crude
Stanford and SLAC National Accelerator Laboratory jointly run the world's leading program for isolating and studying diamondoids -- the tiniest possible specks of diamond. Found naturally in petroleum fluids, these interlocking carbon cages weigh less than a billionth of a billionth of a carat (a carat weighs about the same as 12 grains of rice); the smallest ones contain just 10 atoms.
5-May-2016 SLAC's historic linac turns 50 and gets a makeover
Since the Department of Energy's SLAC National Accelerator Laboratory powered up its 'linac' half a century ago, the 2-mile-long particle accelerator has driven a large number of successful research programs in particle physics, accelerator development and X-ray science. Now, the historic particle highway is getting a makeover that will pave the way for more groundbreaking research.
27-Apr-2016 Math helps scientists capture molecules in motion
Using data from the world's most powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory, an international team of scientists has made a crucial advance in analyzing ultrafast motions of molecules. They developed a computational method that increases the accuracy of this analysis 300 times -- to one femtosecond, which is a millionth of a billionth of a second.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
