A new layer of sensitivity
Fermilab scientists are adding a new front line to the battery of sensors inside the giant DZero detector. They've just completed the design of a new set of sensors, to be installed in a very confined space, which will give new life to the experiment.

DZero breaks new ground in global computing efforts
Searching for subatomic particles very much resembles the often-cited search for the needle in the haystack. Since the beginning of Collider Run II in March 2001, DZero scientists have collected more than 550 million particle collisions. The data fill five stacks of CDs as high as the Eiffel tower--storage cases not included. And the (hay)stacks are growing every day.

NLC collaboration reaches critical high-power X-band goal
The team, part of the U.S.-Japanese Next Linear Collider-Global Linear Collider collaboration, is working on X-band accelerator technology (for the so-called "warm" linear collider). The international particle physics community is also considering another technology option for the linear collider: superconducting radiofrequency technology, being pursued by the TESLA collaboration led by DESY in Germany.

Are we ready for the dark side?
Simply put, dark energy is a mystery. The expansion of the universe is accelerating, and theorists believe that dark energy is the driving force behind it. Evidence shows that dark energy makes up approximately 70 percent of the universe, meaning 25 percent is dark matter and 4 percent is matter made of atoms.

Nuclear renaissance
Growing levels of atmospheric carbon dioxide are raising concerns of global warming and sparking renewed interest in nuclear power. Unlike coal- and gas-fired power plants, nuclear power plants provide electricity without emitting carbon dioxide. They could also enable a hydrogen economy.

RAPTOR science
A small robotic observatory system, called RAPTOR, is poised to take movies of fleeting astrophysical events. These movies will help astronomers better understand planetary systems, stars, galaxies, and the universe. Some of RAPTOR's data analysis techniques can also be applied to defense problems.

Nanofluids? Cool!
Adding nanoscale particles--so small they are measured in billionths of a meter--to conventional liquids holds the promise of more efficient cooling for engines, machinery and supercomputers. These "nanofluids" have increased by up to 150 percent the heat-transfer rate of fluids.

PPPL researchers study plasma sterilization
Hundreds of billions of plastic food and beverage containers are manufactured each year in the U.S. All of these packages must undergo sterilization, which at present is done using high temperatures or chemicals. Both of these methods have drawbacks. What if a new method could be found that eliminated the need for chemicals or heat-resistant plastics?

By-line from the frontlines
The process of science--the building of instruments, analysis of raw data, debugging of computer code, cleaning of lenses--usually doesn't make it to the headlines. You hear "Scientists Find Top Quark," but never, "Scientists Find New Use for Mylar Tape." Experimental physicists know better than anyone the tangled marriage of serendipity and tedium in nailing down a discovery.

Two mysteries, one solution?
Using detectors chilled to near absolute zero, from a vantage point half a mile below ground, physicists of the Cryogenic Dark Matter Search announced the November 12 launch of a quest that could lead to solving two mysteries that may turn out to be one and the same: the identity of the dark matter that pervades the universe, and the possible existence of supersymmetric particles.

Longest linac makes the world's shortest electron bunches
Researchers at the U.S. Department of Energy's Stanford Linear Accelerator Center used the world's longest linear accelerator to develop the world's shortest bunches of electrons. Conversion of these bunches into bright, short pulses of X-ray light enables researchers to directly observe atomic motion never seen before in solids and liquids--allowing for instantaneous snapshots of simple chemical reactions in progress.

Superconducting magnets
When you cool a piece of metal below a critical temperature, something magical happens. The atoms begin passing along electrons with zero resistance. People in the know refer to this rare state as "superconductivity."

Twenty years at the energy frontier
The Tevatron began operations in late 1983 when the E715 experiment initiated the use of the world's highest-energy beams. Since then more than forty fixed-target experiments have used Tevatron beams of protons, pions, muons, photons, hyperons and neutrinos to expand our knowledge of particles and forces.

Supernovae shape up for cosmology
A collaboration among the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the European Southern Observatory, and the University of Texas has yielded the discovery that Type 1a supernovae do not explode spherically. This discovery marks the first time that the intrinsic polarization of a normal Type 1a supernova has been detected.

Pentaquark: New evidence of an exotic five-quark particle
Results of an international research collaboration have yielded convincing evidence of a subatomic particle consisting of five quarks. The results of the research--conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility--were announced at the Conference on the Intersections of Particle and Nuclear Physics in May 2003.

From Georgia with innovation: A profile of Jefferson Lab staff scientist Youri Sharabian
By the time he was in 7th grade, Sharabian had built a small workshop in his family's basement. When his father came home from work with a design for small engine springs, but complained of the difficulties in making them quickly, Sharabian was intrigued and subsequently fashioned a specialized apparatus capable of winding wire accurately and rapidly. His father was so impressed that the innovation was adopted with minor modifications directly onto the factory floor.

Marie & Pierre Curie’s granddaughter, Hélène Langevin-Joliot, visits the United States
Jefferson Lab science writer Melanie O'Byrne spoke with Langevin-Joliot during the recent International Symposium for Spinal Radiography at Georgetown University. In the following excerpt, she discusses her work, passion for science, and remarkable family history. She is a respected nuclear physicist from the Institute of Nuclear Physics at Orsay, the laboratory set up by her parents, Irène and Frédéric Joliot-Curie, who won a Nobel Prize for chemistry in 1935 for their discovery of artificial radioactivity.
