ATLAS (detector)

The ATLAS detector is a massive scientific instrument at CERN designed to observe and analyze the particles produced when protons collide at extremely high energies within the Large Hadron Collider. It functions like a sophisticated three-dimensional camera, capturing data from these collisions to study fundamental particles and forces. By examining these interactions, ATLAS helps physicists explore the basic building blocks of matter, verify theoretical predictions, and search for new phenomena such as dark matter or extra dimensions. Its complex layers and technologies enable detailed reconstruction of particle trajectories, energies, and identities in these fleeting, high-energy events.
