Particle accelerators, also known as particle colliders or atom smashers, have been responsible for some of the most exciting physics findings over the past century, including the discovery of the ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.

The ATLAS experiment at the Large Hadron Collider is one of the machine's two big all-purpose detectors. It took three years for the world's most powerful particle accelerator, the Large Hadron ...

Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...

When the Large Hadron Collider (LHC) began operations, a small but noisy group of people tried to stop it out of fear. Their reasoning: The energies produced as protons slammed into each other at ...

Two of the largest machines ever conceived by scientists are being reported by one of the world's leading experts on particle colliders, the massive and expensive machines used to explore inner ...

Europe is pushing forwards with plans to build a 91-kilometre-long, 15-billion-swiss-franc (US$17-billion) supercollider underneath the French and Swiss countryside. The machine would allow ...

The LHC today began running 7TeV collisions for the first time. In the instant that its detectors register the events associated with a collision, the challenges move from the hardware realm into ...

Move over, Large Hadron Collider. A new atom smasher could one day slam particles into each other at even more mind-bogglingly high-energy levels than the massive underground ring near Geneva. The new ...
