Fermilab Tours

All registrants will be treated to tours of Fermilab’s cutting-edge experiments and facilities. Anticipated tour stops include:

The Accelerators

	The Linac (Linear Accelerator)
	The Tevatron Accelerator
	The four-story tall, 5,000 ton Collider Detector at Fermilab (CDF)
	The 'Broken Symmetry' gateway sculpture frames Wilson Hall.

The Linac, approximately 500 feet long, accelerates charged hydrogen ions to about 70% of the speed of light. The ions then pass through a carbon foil, which removes electrons from the hydrogen ions, creating positively charged protons.

The protons continue to accelerate as they travel through the Booster, a circular accelerator, and the Main Injector, which accelerates protons, delivers protons for antiproton production, and accelerates antiprotons coming from the antiproton source. Then the particles enter the Tevatron.

Fermilab’s Tevatron is currently the most powerful particle accelerator in the world. Protons and antiprotons circle around the four-mile accelerator at almost the speed of light in opposite directions, before colliding in one of the detectors.

The Detectors

Protons and antiprotons accelerated in the Tevatron collide head-on inside the huge Collider Detector at Fermilab (CDF) and the DZero detector, where their collisions are studied. International collaborations of scientists use the information to search for evidence of new physics, such as the Higgs Particle; measure and study the decay of known particles such as electrons, muons, and taus; and measure the production properties of known particles and jets.

Protons from the Tevatron are also used to create a beam of elusive neutrino particles. The Main Injector Neutrino Oscillation Search (MINOS) experiment shoots this beam underground through the "near" detector located underground at Fermilab to a "far" detector located in a historic mine 450 miles away, and is designed to observe the phenomena of neutrino oscillations, an effect related to neutrino mass.

The Lederman Science Education Center

The Lederman Science Center, named for Nobel Laureate, former Fermilab Director, and Congress plenary speaker Leon M. Lederman, is host to several interactive exhibits including ones on accelerators and detectors. This facility is used for education and outreach to children of all ages, giving them hands-on experience exploring how Fermilab physicists understand nature's secrets.

And More!

While at Fermilab you'll also get to see a number of unique sculptures that represent the intersection of art and science, floor-to-ceiling blackboards covered in equations and diagrams, award-winning wetlands, distinctive architecture, and maybe even Fermilab's herd of American bison.

About Fermilab

Fermilab, originally named the National Accelerator Laboratory, was commissioned by the U.S. Atomic Energy Commission, under a bill signed by President Lyndon B. Johnson on November 21, 1967. Founding Director Robert R. Wilson committed the laboratory to firm principles of scientific excellence, esthetic beauty, stewardship of the land, fiscal responsibility and equality of opportunity. Universities Research Association built the laboratory, and has operated the facility under those principles since its founding.

On May 11, 1974, the laboratory was renamed in honor of 1938 Nobel Prize winner Enrico Fermi, one of the preeminent physicists of the atomic age. Fermi's widow, Laura Fermi, spoke at the dedication ceremonies.

Two major components of the Standard Model of Fundamental Particles and Forces were discovered at Fermilab: the bottom quark (May-June 1977) and the top quark (February 1995). In July 2000, Fermilab experimenters announced the first direct observation of the tau neutrino, the last fundamental particle to be observed. Filling the final slot in the Standard Model, the tau neutrino set the stage for new discoveries and new physics with the inauguration of Collider Run II of the Tevatron in March 2001.

The Tevatron, four miles in circumference and originally named the Energy Doubler when it began operation in 1983, is the world's highest-energy particle accelerator. Its 1,000 superconducting magnets are cooled by liquid helium to -268 degrees C (-450 degrees F). Its low-temperature cooling system was the largest ever built when it was placed in operation in 1983. The American Society of Mechanical Engineers has designated the Tevatron cryogenic system an International Historic Mechanical Engineering Landmark.

Fermilab has added the two-mile Main Injector accelerator to increase the number of proton-antiproton collisions in the Tevatron, greatly enhancing the chances for important discoveries in Run II. The two apartment building-sized collider detectors, CDF and DZero, have undergone extensive upgrades during the nearly decade-long preparations for Run II.

	Fermilab’s herd of American bison

Fermilab's 6,800-acre site was originally home to farmland, and to the village of Weston. Some of the original barns are still in use by the laboratory, for purposes ranging from storage to social events. A small burial ground, with headstones dating back to 1839, has been maintained in the northwest corner of the site. Robert Wilson was buried in the Pioneer Cemetery following his death on January 16, 2000 at the age of 85.

Among Wilson's early imprints on the lab was the establishment of a herd of American bison, symbolizing the Fermilab's presence on the frontiers of high-energy physics, and the connection to its prairie origins. The herd stands today, and new calves are born every spring.
