9-Dec-2015 To get more oomph from an electron gun, tip it with diamondoids
They sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning equipment and particle accelerators, to name a few important uses. Now scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have figured out how to increase these electron flows 13,000-fold by applying a single layer of diamondoids -- tiny, perfect diamond cages -- to an electron gun's sharp gold tip.
8-Dec-2015 Innovation boosts study of fragile biological samples at SLAC's X-ray laser
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a simple new way to study very delicate biological samples -- like proteins at work in photosynthesis and components of protein-making machines called ribosomes -- at the atomic scale using SLAC's X-ray laser.
23-Nov-2015 Atom-sized craters make a catalyst much more active

16-Nov-2015 X-ray microscope reveals 'solitons,' a special type of magnetic wave
Researchers used a powerful, custom-built X-ray microscope at the Department of Energy's SLAC National Accelerator Laboratory to directly observe the magnetic version of a soliton, a type of wave that can travel without resistance. Scientists are exploring whether such magnetic waves can be used to carry and store information in a new, more efficient form of computer memory that requires less energy and generates less heat.
11-Nov-2015 SLAC goes to bat for science at Discovery Day
The annual Discovery Day at AT&T Park was yet again a grand slam for science: About 35,000 visitors flocked to the ballpark of the San Francisco Giants on Nov. 7 to attend the fifth edition of the family-friendly science fair. With 150 exhibits and activities, science and technology organizations from across the Bay Area made science fun and accessible to the public.
3-Nov-2015 A record-setting way to make transparent conductors: Spread them like butter on toast
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have shown they can make flexible, transparent electrical conductors with record-high performance for use in solar cells, displays and other devices by spreading polymers on a clear surface with a tiny blade, like a knife spreading butter on toast.
2-Nov-2015 First neutrino sightings by MicroBooNE
The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter's dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
29-Oct-2015 Scientists get first glimpse of conductivity that could break size barriers for memory
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have made the first direct images showing that electrical currents can flow along the boundaries between tiny magnetic regions of a material that normally doesn't conduct electricity. The results could have major implications for magnetic memory storage.
22-Oct-2015 Stanford and SLAC celebrate Arthur Bienenstock
Arthur 'Artie' Bienenstock, professor emeritus at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, was honored with an all-day symposium in recognition of his outstanding contributions to science, academia, graduate student education and US science policy.
16-Oct-2015 Jonathan Dorfan and David Hitlin receive 2016 Panofsky Prize
The American Physical Society has honored two key figures of the BABAR particle physics experiment at the Department of Energy's SLAC National Accelerator Laboratory with the 2016 W.K.H. Panofsky Prize in Experimental Particle Physics: SLAC Director Emeritus Jonathan Dorfan and California Institute of Technology Professor David Hitlin. They share the award with Stephen Olsen and Fumihiko Takasaki, two lead researchers of the Belle experiment in Japan.
13-Oct-2015 Ming Yi awarded L'Oréal USA For Women in Science Fellowship
Former Stanford University graduate student Ming Yi has been awarded the $60,000 L'Oréal USA For Women in Science Fellowship, which is given to five US-based women each year as part of an effort to raise awareness of women's contributions to science and identify exceptional female researchers to serve as role models.
25-Sep-2015 Feng Lin wins Spicer Award for smart window, battery research
Feng Lin, a former postdoctoral researcher at Lawrence Berkeley National Laboratory, has been selected to receive the annual William E. and Diane M. Spicer Young Investigator Award for X-ray experiments at the Department of Energy's SLAC National Accelerator Laboratory that led to new approaches in the design of energy-efficient, color-changing 'smart' windows and high-capacity lithium-ion batteries.
23-Sep-2015 Mysterious neutrinos take the stage at SLAC
To find out more about the elusive particles and their potential links to cosmic evolution, invisible dark matter and matter's dominance over antimatter in the universe, the Department of Energy's SLAC National Accelerator Laboratory is taking on key roles in four neutrino experiments: EXO, DUNE, MicroBooNE and ICARUS.
17-Sep-2015 Roopali Kukreja wins 2015 Klein Award for X-ray work
Roopali Kukreja, a former researcher at the Department of Energy's SLAC National Accelerator Laboratory who received her Ph.D. in materials science at Stanford University last year, will be honored during a SLAC conference next month with the Melvin P. Klein Scientific Development Award for her X-ray studies of nanoscale magnetic and electrical properties of materials.
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. They observed, for the first time, its shockingly fast transformation into the mineral stishovite -- a rare, extremely hard and dense form of silica.
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. The result, which revealed a surprising loss of current along the way, is an important step toward realizing a next-generation breed of electronics known as 'spintronics.'
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.
