The ATLAS Experiment

 

When completed in 2005 the Large Hadron Collider at CERN in Geneva will be the world's most powerful particle accelerator.

By colliding protons with energies of seven million million electron volts, it will recreate the conditions existing just after the ³Big Bang² and allow the study of exotic new physics.

The ATLAS experiment consists of a series of nested electronic detectors designed to observe the debris from these collisions, which will occur 40 million times every second, and to measure their properties (energy, momentum, etc.).
