ATLAS Experiment: Calorimeters



Calorimeters measure the energy a particle loses as it passes through the detector. It is usually designed to stop entire or “absorb” most of the particles coming from a collision, forcing them to deposit all of their energy within the detector.

Calorimeters typically consist of layers of “passive” or “absorbing” high-density material – for example, lead – interleaved with layers of an “active” medium such as solid lead-glass or liquid argon.
