Fermi National Accelerator Laboratory

Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a US Department of Energy national laboratory specializing in high-energy particle physics. As of January 1, 2007, Fermilab is operated by the Fermi Research Alliance, a joint venture of the University of Chicago, Illinois Institute of Technology and the Universities Research Association (URA). Fermilab is a part of the Illinois Technology and Research Corridor. Fermilab's Tevatron was a landmark particle accelerator; at 3.9 miles (6.3 km) in circumference, it was the world's second largest energy particle accelerator (CERN's Large Hadron Collider is 27 km in circumference), until being shut down on September 30, 2011. In 1995, both the CDF and DØ (detectors which utilize the Tevatron) experiments announced the discovery of the top quark. In addition to high energy collider physics, Fermilab is also host to a number of smaller fixed-target and neutrino experiments, such as MiniBooNE (Mini Booster Neutrino Experiment), SciBooNE (SciBar Booster Neutrino Experiment) and MINOS (Main Injector Neutrino Oscillation Search).

Dark Energy Survey completes six-year mission

After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey (DES) will finish taking data tomorrow, on Jan. 9.

From turkeys to turn-keys

Last week, millions of Americans unwrapped a shrink-wrapped turkey for Thanksgiving. If so, they owe thanks to electron beams, which made the shrink-wrapping possible. But the electron beam can do a lot more: It can sterilize ...

Modern modulators for Fermilab accelerators

Take a walk along the hall that houses Fermilab's linear accelerator, and you'll see tall sets of brightly lit shelves that resemble fancy vending machines. But instead of snacks and beverages, they hold boxy structures that ...

Mapping the universe in 3-D

In 1998, scientists discovered that the universe's expansion is accelerating. Physicists don't know how or why the universe is accelerating outward, but they gave the mysterious force behind this phenomenon a name: dark energy.
