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.

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.

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.

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.

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.

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.'

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.
