Link on Title and internal “color reference links” will highlight links to subject locations. Well worth the visit.

 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 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:

• the trigger system – selecting 100 interesting events per second out of 1000 million others
• the data acquisition system – channeling the data from the detectors to the storage
• the computing system – analysing 1000 Million events recorded per year
