http://www.facebook.com/ScienceReason ... CERN/ATLAS Experiment: Recreating Big Bang.

Mapping the Secrets of the Universe: ATLAS is a particle physics experiment at the Large Hadron Collider at CERN. The ATLAS detector is searching for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, unification of fundamental forces, and evidence for dark matter candidates in the Universe.

ATLAS is one of two general-purpose detectors at the LHC. It will investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter. ATLAS will record sets of measurements on the particles created in collisions - their paths, energies, and their identities.

This is accomplished in ATLAS through six different detecting subsystems that identify particles and measure their momentum and energy. Another vital element of ATLAS is the huge magnet system that bends the paths of charged particles for momentum measurement.

The interactions in the ATLAS detectors will create an enormous dataflow. To digest these data, ATLAS needs a very advanced trigger and data acquisition system, and a large computing system. More than 2900 scientists from 172 institutes in 37 countries work on the ATLAS experiment.
