Studies of the performance of the ATLAS detector using cosmic-ray muons

Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector. Cosmic-ray muons can penetrate to the cavern and deposit energy in all detector subsystems. Such events have played an i...

Cosmic-ray muons can penetrate to the cavern and deposit energy in all detector subsystems.
