Extreme Plasma Theories Are Being Put To The Test
2012-08-07 13:20:41

The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year old model used to explain how ions influence each other's behavior in a dense plasma. The results should benefit a wide range of fields, from research aimed at tapping nuclear fusion as an energy source to understanding the inner workings of stars. The study also demonstrates the unique capabilities of the Linac Coherent Light Source (LCLS) X-ray laser at the U.S. Department of Energy...

BELLA Laser Achieves One Pulse Per Second For World Record Power

BELLA Laser Achieves One Pulse Per Second For World Record Power As Berkeley Lab´s laser plasma accelerator project BELLA nears completion, its drive laser has delivered one petawatt — a quadrillion watts — of peak power once each second, a world record for laser performance On the night of July 20, 2012, the laser system of the Berkeley Lab Laser Accelerator (BELLA), which is nearing completion at the U.S. Department of Energy´s Lawrence Berkeley National...

X-ray Imaging To Observe Running Batteries In Action
2012-07-18 09:56:44

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries — a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost. But lithium-sulfur technology has a major drawback: After a few dozen cycles of charging and discharging, the battery stops working. "The cycle life of...

Soot Particles Measured In Flight
2012-06-27 12:53:57

"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...

Aerosol Structures Exposed By X-ray vision
2012-06-27 12:48:29

Laser probes microscopic components of air pollution Researchers at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion...

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma. Ultrafast phase...

3.4 Billion Pixel Telescope Plans Move One Step Further
2012-04-26 13:11:13

Lee Rannals for RedOrbit.com The U.S. Department of Energy has given the go ahead for a proposed 3.4 billion pixel Large Synoptic Survey Telescope (LSST) to move on to the next step of development. Now that the project has received approval from the department, it will begin the engineering design, scheduling, and budgeting portion of the project. The telescope received a "Critical Decision 1" approval, making a big step toward being one of the widest, fastest and deepest view...

Researchers from Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons" — exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices. "The behavior of electrons in materials is at the heart of essentially all of today's technologies," said Hari Manoharan, associate professor of physics at Stanford and a member of SLAC's...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
