19-Jul-2007 Researchers' hottest new laser beams 14.2kW
On Oct. 26, Free-Electron Laser (FEL) team members knew they were within reach of a goal they'd pursued for two years. They were aiming to produce 10 kW of laser light at an infrared wavelength of 1.61 microns. On that day, they blew past the milestone to produce 11.7 kW. Just four days later, on Oct. 30, they coaxed another two kW out of the machine setting the record even higher at 14.2 kW.
9-Jul-2007 Lab enhances scientific data sharing with cutting-edge connection
In early 2005, researchers affiliated with Hall B wanted to transfer raw data from a recent experiment from the tape silo to computers offsite -- a task that without interruption would have taken the Lab's existing network connection almost seven days. Jefferson Lab's newly upgraded network connection is able to transfer data at a rate of up to 10 Gigabits per second, so that same transfer can now be completed in just 2.5 hours.
5-Jul-2007 Big bite is reborn
At Jefferson Lab's recent Users Meeting, DOE's Dennis Kovar and NSF's Brad Keister emphasized the funding agencies' commitment to pursuing a cohesive nuclear physics research program in the United States. For instance, Jefferson Lab is funded by DOE; however, NSF provides for many of the Lab's Users and students and some of the instrumentation used in experiments, such as the recently upgraded BigBite spectrometer.
22-Mar-2007 Data-intensive computing key to predictive science
The ability to protect the nation
from terrorist attacks, discover the
hidden secrets of genes and monitor
and control the electrical power grid
requires the ability to process and
analyze massive amounts of data and
information in real time.
22-Mar-2007 Balancing oil and environment... responsibly
As the price of oil continues to fluctuate
unpredictably and nears the brink of depletion,
pursuing unconventional oil supplies, such as oil
shale, oil sands, heavy oils, and oils from biomass and
coal, has become increasingly attractive. Of particular
significance to the American way is that our continent
has significant quantities of these resources.

22-Mar-2007 Digging into dirt -- Subsurface science at PNNL
Imagine drinking water that has
dripped through the sponge you've just
used to clean the breakfast dishes. This
is happening around the world. Rain
and snow pass through soil polluted
with pesticides, poisonous metals and
radionuclides into the underground
streams that supply rivers, lakes and
21-Mar-2007 From Russia with love
Ensuring that hydrogen-burning
engines are explosion-proof is one of
the barriers to establishing a hydrogen
economy. A tiny Russian-designed
hydrogen sensor that can quickly detect
and warn of a gas leak may be one of the
technologies to help catapult the world
into the hydrogen age.
9-Mar-2007 PNNL receives national safety award
Pacific Northwest National
Laboratory has been recognized as
one of America's Safest Companies
as featured in Occupational Hazards
magazine's November 2006 issue. Each
year, the honor is given to a group
of companies that demonstrate their
management-supported safety processes,
involvement from staff and innovative
solutions to safety challenges.
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.
