Antimatter Atoms Successfully Stored for the First Time

Atoms of antimatter have been trapped and stored for the first time by the ALPHA collaboration, an international team of scientists working at CERN in Switzerland. Berkeley Lab researchers made key contributions to the effort, including the design of the trap’s crucial component—an octupole magnet—and computer simulations needed to identify real antihydrogen annihilation events against a noisy background.

Superconductors Face the Future

With support from the American Recovery and Reinvestment Act (ARRA), Berkeley Lab’s Accelerator and Fusion Research Division is building a test facility for the superconducting magnets of the future. The Large Dipole Facility will provide a critical research tool for testing potential new materials including high-temperature superconductors. Despite their promise, the new materials pose plenty of problems and challenges.

Wriggling Neutrinos Caught in the Act

The first direct observation of a muon neutrino turning into a tau neutrino at the Gran Sasso underground laboratory in Italy confirms that indeed neutrinos do oscillate among “flavors.” Berkeley Lab’s Kevin Lesko says the result “really nails the neutrino oscillation phenomenon.”

Bay Area’s Berkeley Lab Plays a Major Role as the Large Hadron Collider Enters the Realm of New Physics

Beams of protons were brought together in the first focused collisions on Tuesday, March 30, at CERN’s Large Hadron Collider. The world’s record collisions open a new realm of high-energy physics.

Beams are Back in the Large Hadron Collider

After more than a year of repairs, the Large Hadron Collider located at the CERN laboratory near Geneva, Switzerland is back on track to create high-energy particle collisions that may yield extraordinary insights into the nature of the physical universe.

Angels, Demons, and Antihydrogen

There’s nothing fictional about antimatter. It’s all around us, all the time. Researchers know how to create and store antiparticles, and members of Berkeley Lab’s Accelerator and Fusion Research Division have even helped make antihydrogen atoms at CERN. But gathering enough to fuel a rocket or make a bomb would take so much energy that no one (including the Vatican) needs to worry.

Closer to the First Millionth of a Second

The ALICE detector at CERN’s Large Hadron Collider will study the fireballs that result when energetic lead ions collide, recreating conditions like those when the universe was just a millionth of a second old. An ALICE instrument called EMCal will signal the most interesting events. Designed by an international collaboration spearheaded by scientists and engineers at Berkeley Lab and other U.S. institutions, EMCal is now on its way to completion.

First Beam for Large Hadron Collider

At 1:25 a.m. Pacific Time an international collaboration of scientists in Switzerland sent the first beam of protons zooming at nearly the speed of light around the world’s most powerful particle accelerator, CERN’s Large Hadron Collider. Berkeley Lab scientists and engineers were among the contributors to the giant machine.
