BNL Contribution to ATLAS |
 | | The machine, dubbed ATLAS (A Toroidal LHC ApparatuS), is one of four facilities to be located at a powerful accelerator, the Large Hadron Collider (LHC), now under construction near Geneva, in Switzerland. |
 | | The LHC, due to begin operation in 2006, consists of two circular vacuum pipes in which protons will travel in opposite directions and collide at nearly the speed of light with a total collision energy of 14 tera-electron volts (TeV), or 14 trillion times the typical energy of an electron. |
 | | Brookhaven scientists are making and testing parts of two components of ATLAS: the liquid argon calorimeter, which detects and measures electrons and photons, and the muon detectors, which detect very penetrating particles called muons. |
