Coal: An energy bridge to the future
For years, coal drove the transportation business in this country, and it may be poised for a comeback. A hundred years ago, steam engines burned tons of coal as they pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel to fill our gas tanks and move cars and trucks.

ScalaBLAST solves problems in record time
Scientists are dedicated to making discoveries that influence our world, but making these discoveries takes time. It took Albert Einstein 16 years to express his general theory of relativity. Benjamin Franklin was first introduced to electricity experiments on a trip to Boston in 1746, but his famous lightning rod experiment didn't occur until six years later -- and he knocked himself unconscious more than once in the process.

CEBAF's beam polarization gets a boost
In the last year, the polarization of CEBAF's electron beam has increased by more than 10 percent to over 86 percent polarization. This vast improvement in polarization, or the percentage of electrons spinning in one direction, has reduced the amount of beam time needed to complete precision experiments like G-Zero and HAPPEx. It's the result of work by the Electron Gun Group, which has spent the last two years pushing the boundaries of photocathode physics.

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.

Determining how spin arises in the nucleon
In scattering experiments, the momentum transferred to a nucleon target from the incident electron is a primary characteristic of the interaction. Large momentum transfer reactions probe the fundamental quarks and gluons (collectively known as partons) that make up the nucleon.

Hypernuclei at Jefferson Lab
In 1827, Robert Brown observed that pollen grains floating in a drop of water jiggled constantly. The phenomenon became known as Brownian motion. Over 75 years later, Einstein proposed that the pollen grains were being jostled by the molecules of water. The impurity (pollen grains) Brown had added to the water allowed Einstein to deduce the presence of individual water molecules and describe at least one of their properties.

Spin identity
Spin is an essential and fascinating phenomenon in the physics of elementary particles. Spin was first defined by Goudsmit and Uhlenbech in 1925, and has played a dramatic role in elementary particle physics, sometimes refuting theories and at other times supporting them. During Experiment E99-117 at Jefferson Lab, an international collaboration collected precision data on the spin of the neutron. Results from this experiment provide evidence that our current understanding of spin is not totally valid.

Using instrumentation built in collaboration with JLab
College of William & Mary (CWM) scientists have found that an equivalent dose of potassium iodide five times higher than the FDA-recommended dose for humans, in the event of a nuclear accident, is needed to protect small animals effectively from radioactive iodide in medical imaging procedures. This study was performed as part of a long-term animal nuclear imaging project conducted by of biology, physics and applied science researchers from CWM and Jefferson Lab.

Pocket-sized physics detector does big science
How do quarks and gluons, the elementary constituents of all matter, combine to form the protons and neutrons in the nucleus of the atom? This is a fundamental unsolved question in nuclear physics that researchers at Jefferson Lab are working to answer. The internal structure of the proton has been studied for several decades, and scientists have learned a great deal. However, much less is known about the structure of the neutron.

Spin structures of protons and neutrons
Just as a top spins on a table, the tiny quarks inside protons and neutrons also spin. Now a complex calculation by theoretical nuclear physicists at Jefferson Lab has revealed that a quark's spin may be altered by the surroundings of the proton or neutron in which it resides. This surprising result, recently published in the journal, Physical Review Letters, may lead to new insights about how ordinary matter is constructed.
