Brookhaven & the LHC

The world's most powerful particle accelerator, the Large Hadron Collider (LHC) in Switzerland, powers unprecedented explorations of the deepest mysteries of the universe. In addition to serving as the U.S. host laboratory for the ATLAS experiment at the LHC, Brookhaven National Lab plays multiple roles in this international collaboration, from construction and project management to data storage and distribution.

Brookhaven and ATLAS

Brookhaven physicists and engineers are participating in one of the most ambitious scientific projects in the world—helping to operate a machine the size of a seven-story building that will open new frontiers in the pursuit of knowledge about elementary particles and their interactions. The machine, dubbed ATLAS, is designed to detect particles created by proton collisions at the Large Hadron Collider. One of its main goals is to look for a particle called the Higgs boson, which gives mass to the basic building blocks of all matter. The high-energy collisions within ATLAS may also offer breakthrough insights into new physics theories that provide a better understanding of the origin of the universe. More...

Future Upgrades

Much of the work for the U.S. LHC Accelerator Research Program (LARP) uses Brookhaven’s Relativistic Heavy Ion Collider (RHIC) as a “test bed” for the beam-based development of devices destined for the LHC  More..
