ATLAS Experiment CERN

ATLAS Detector Image

The ATLAS detector consists of four major components
(place your cursor over the links below to identify the location of the components):
  • inner detector (yellow) - measures the momentum of each charged particle
  • calorimeter (orange and green) - measures the energies carried by the particles
  • muon spectrometer (blue) - Identifies and measures the momenta of muons
  • magnet system (grey) - bending charged particles for momentum measurement

The interactions in the ATLAS detectors will create an enormous dataflow. To digest this data we need:
