5-Oct-2006 ORNL's High Flux Isotope Reactor prepares to make 'cold' neutrons
The High Flux Isotope Reactor at the Department of Energy's Oak Ridge National Laboratory has passed a major milestone in its quest to become one of the world's leading sources of 'cold' neutrons for advanced scientific research. Once fully operational, the reactor will combine with the laboratory's Spallation Neutron Source to make Oak Ridge the world's center for neutron sciences.
8-Aug-2006 Jefferson Lab's newest cluster computer takes shape
Unlike a regular computer -- whose "brain" consists of one or perhaps two processors -- a cluster computer's brain can contain hundreds or even thousands of individual processors, called nodes -- all wired together. To solve a problem, the cluster splits the problem into parts, and each node computes its designated part and shares the result with other nodes to produce the final solution.
20-Jul-2006 On the leading edge
The Accelerator Division's Institute
for Superconducting Radiofrequency
(SRF) Science & Technology
is a world leader in SRF accelerator
technology research and design. Now
the newest idea out of the Institute
may revolutionize the way accelerating
cavities are produced -- making
the manufacturing process faster and
cheaper, while producing cavities that
could potentially outperform any other
niobium cavities ever tested.
20-Jul-2006 Detector Group builds imaging device for German Research Center
Jefferson Lab Detector Group members traveled to Heidelberg, Germany, to assemble and bring on-line a small-animal imaging device the group developed and built for the German Cancer Research Center. Work on the project began in June 2004. The device is similar other small animal imaging gamma cameras developed by the Detector Group; however, this imager design is based on a new concept developed by Vladimir Popov which resulted in highly improved detector performance.
29-Jun-2006 Technology demonstration thwarts fictitious terrorist attack
The pace was intense as data flowed in from sources across the world -- a spike in radiation from a ground-based indicator in Pakistan, an unexplained outbreak of plague in India, and a disturbing convergence of travel plans among suspected terrorists. Information Analysis Center analysts agreed the evidence indicated a well planned terrorist attack was imminent in downtown Seattle. Local law enforcement was quickly dispatched, capturing the suspected terrorists as they attempted to smuggle a chemical and radiation dispersing bomb into the city.
29-Jun-2006 Lightweight materials pave the road for energy-efficient vehicles
In efforts to shorten the long road to fuel efficiency, researchers at Pacific Northwest National Laboratory are working to develop cost-effective, high-strength, lightweight materials that will reduce vehicle weight without compromising cost, performance or safety.
29-Jun-2006 Catalysis: The science behind sustainable energy
About 60 percent of the things we wear or use are produced by processes that depend on catalysis. Catalysts are substances that modify chemical reaction rates and remain unchanged afterward.
Catalyst technologies affect nearly all areas of the chemical and petroleum industries with an economic impact estimated at more than $10 trillion per year worldwide. Now more than ever, innovative and improved catalyst technologies are in demand for new energy production processes to ease the United States' dependence on imported resources.
12-Jun-2006 Managing the Soviet legacy
An intact nuclear weapon is stolen and detonated. A terrorist group somehow steals, purchases, or produces fissile material and fabricates a crude bomb, called an improvised nuclear device, which the group threatens to detonate if its demands are not met.
12-Jun-2006 Science for security
Since the terrorist attacks of September 11, 2001, national security has become a priority mission of the Department of Energy. This mission, which in addition to public safety focuses on the protection of America's economic and energy security assets, is supported by an increasingly robust program of technological innovation.
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.
