'Dear Monica...'
Monica Charpentier, a junior at Dulaney High School in Timonium, Maryland submitted a question about the property of charge. "Just what is it?" she wanted to know. Her query found its way to Fermilab theorist Andreas Kronfeld, who welcomed the opportunity to follow her questions and insights to succeeding levels of complexity.

Exploring the invisible universe
Scientists at Fermilab are deeply involved in unraveling the secrets of this invisible universe. An experiment called the Cryogenic Dark Matter Search looks for new types of particles that could be building blocks of dark matter. The Sloan Digital Sky Survey has begun to record a detailed three-dimensional map of the sky, providing vast amounts of data on clusters of galaxies that seem to harbor black holes and dark matter.

A new generation of supercomputers
Using paper and pencil, theorists have captured new ideas, revealed intricate mathematical relations and carried out page-long calculations. But times have changed. For many applications, physicists now prefer to attack their models and equations with the best computers available. The Fermilab theory group became one of the top players in the area of computational physics with the installation of a supercomputer called ACPMAPS in 1989.

Faster inspection of laser coatings
Lasers have been a Lawrence Livermore specialty almost since the first laser flashed in 1960. Dealing with the challenges that arise as these lasers get bigger and more powerful is, of necessity, a specialty too.

Opening new markets for agricultural byproducts
Researchers at Pacific Northwest and ADM have developed processes that will reclaim greater value from the hulls of corn kernals by separating the hull's fiber into its basic components—lipids, carbohydrates, proteins. These products will then be used to produce fuel ethanol and the building blocks for industrial chemicals, as well as higher value food, feed and consumer products.

Sensible sensors
Joseph Shinar, Ames Laboratory senior physicist, in collaboration with chemist Raoul Kopelman from the University of Michigan, Ann Arbor, has developed a novel, fluorescence-based chemical sensor that is smaller, less expensive and more versatile than existing technology of its kind.

Tevatron luminosity makes an uphill climb
Collider Run II at Fermilab's Tevatron officially began on March 1, 2001. Since Tevatron operations resumed in November, 2001, after a two-month shutdown for accelerator and detector upgrades, luminosity has increased more slowly than hoped for. Fermilab has in place a plan to raise the luminosity to the desired levels by the end of 2002.

Cracking the mystery of cracks
Scientists at the Department of Energy's Pacific Northwest National Laboratory have performed first-of-a-kind, high-resolution examinations of cracks in stainless steel core components from commercial nuclear reactors, dispelling many of the traditionally held beliefs about how cracks develop and spread.

State-of-the-art magnetoelectronics lab puts Ames Lab on thin-film fast track
Tucked away in a small laboratory space on the second floor of Metals Development is new, state-of-the-art research equipment that should help boost Ames Lab researchers David Jiles and John Snyder to the forefront of thin-film research and the newly emerging field of magnetoelectronics.

Painless physics: a particle dialogue
What are electrons, protons and neutrons, how do we define them, how do they fit into the theory of elementary particle physics, the Standard Model—and how do we use them to explore the subatomic world?

Recycling antimatter becomes reality
Antimatter is arguably the rarest stuff Mother Nature provides here on earth. Created in high-energy particle collisions, antiparticles quickly disappear by reacting with ordinary matter. Using powerful accelerators, physicists have learned to produce and control tiny amounts of antimatter. Scientists at Fermilab are now taking a new approach to satisfy the ever-increasing demand for antimatter: they will recycle antiprotons.

Passively safe reactors rely on nature to keep them cool
The basic purpose of reactor safety is to protect the public and plant workers from harmful radiation exposure. The goal of modern safety design is to provide this protection by relying on the laws of nature, rather than on engineered systems that require power to operate, equipment to function properly and operators to take correct actions in stressful emergency situations. To achieve this, you have to remove decay heat, contain radioactive materials, and maintain a proper balance between heat generation and heat removal.

Researchers reach to the skies to reveal the secrets of the stars
In 2003, Argonne scientists will analyze solar wind--single atoms and electrically charged particles from the sun--samples from NASA's Genesis mission in an effort to better understand how the planets formed and how the sun works. If successful, Genesis will become the first mission to return a sample of extraterrestrial material from beyond the moon. These samples will allow a precise measure of the elemental and isotopic composition of our most important star - the sun.

Disorderly superconductors caught in the act
The "granular" nature of superconductivity in underdoped high-temperature superconductors proposed by theorists has had some believers but many skeptics. New observations, reported in the 24 January issue of Nature, may shift how researchers think about these materials.

Neutrino measurement surprises Fermilab physicists
Experimenters at Fermilab's NuTeV (Neutrinos at the Tevatron) experiment measured the ratio of two types of particles—neutrinos and muons—emerging from high-energy collisions of neutrinos with target nuclei.

Fermilab 2002: The outlook
If we learned anything from the year 2001, it is the impossibility of predicting what the next twelve months will bring. Nevertheless, at least one thing seems certain: 2002 at Fermilab will see unique scientific opportunities and extraordinary challenges for physics at the energy frontier.

A clear view
It is as translucent as glass. It comes by train, two railcars every week. Fermilab will receive 250,000 gallons of it, enough to fill a 25-meter swimming pool. What is it? Some of the clearest mineral oil available in the country, intended for the MiniBooNE experiment.

New magnetic refrigerator
Using materials developed at the U.S. Department of Energy's Ames Laboratory, researchers have successfully demonstrated the world's first room temperature, permanent-magnet, magnetic refrigerator. The refrigerator was developed by Milwaukee-based Astronautics Corporation of America as part of a cooperative research and development agreement with Ames Laboratory.

BAM continues amazing development
A material that rivals industrial diamond in hardness continues to amaze the researchers who developed it and attract interest from a variety of industrial sectors. The material represents a breakthrough technology that could have a substantial impact on the machining industry, which spends $300 billion each year in labor and overhead in the United States alone.

Building on success
When researchers at Ames Laboratory developed a compact laboratory furnace, it marked a huge leap forward in the ability to understand what happens to a material's crystal structure as the material is heated and cooled. That success has led to the building of two additional furnaces for other DOE laboratories and a refined design intended to make the furnace easier to operate.

Dirty coal, clean power
Iver Anderson thinks the solution to the rolling power blackouts in California and parts of the East Coast may lie under the rolling black soil of Iowa’s farm country. "Iowa is sitting on top of huge deposits of coal," says Anderson, an Ames Laboratory senior metallurgist. "The problem is that it’s high-sulfur, dirty coal." Anderson and colleagues Bob Terspstra and Brian Gleeson are closing in on a new material to filter the nasty ashes and dust that result from burning "dirty" coal.

Old material makes a new debut
Magnesium diboride is a relatively inexpensive metal compound that can be purchased in powder form from most standard chemical supply companies. Until this year, there was nothing remarkable about it — at least nothing that was known. But the material had never been investigated for superconductivity — whether it had the ability to conduct electricity perfectly, without resistance, when cooled to temperatures near absolute zero (minus 459 degrees Fahrenheit).
