The ATLAS Experiment
The ATLAS
experiment is being built to study proton-proton interactions at the
Large Hadron Collider (LHC)
at the European Laboratory for Particle Physics CERN
near Geneva. It is currently being constructed by about 1700 collaborators
from more than 150 institutes around the world and is due to begin operation
in 2007. One of the most prominent physics goals of ATLAS is to understand
the nature of particle masses. Other important topics are measurements
of CP-violation in the B-system, the study of Top-physics, the
search for supersymmetric particles, and the search for new physics
beyond the
standard model.

| The ATLAS Detector |
The above picture shows a sectional drawing of ATLAS. One can see the 4 major components of the detector, distingished by different colours: The inner tracker (in yellow) to measure the momentum of each charged particle; the calorimeters (green and orange) to measure the energies carried by the particles; the muon sytem (blue) to identify muons and, together with the magnet system (grey), to measure their momenta.
