ATLAS is the largest detector ever constructed for a particle collider: 46 metres long and 25 metres in diameter.

The Inner Detector is the innermost part of ATLAS to see the decay products of the collisions, so it is very compact and highly sensitive.

Calorimeters measure the energy of particles created in high-energy LHC collisions.

The outer layer of the ATLAS experiment is made of muon detectors. They identify and measure the momenta of muons.

ATLAS uses two different types of superconducting magnet systems – solenoid and toroids.

Many cutting-edge technologies developed for the ATLAS Experiment have found new applications in other fields.

Conservation Laws

These laws govern the reactions we observe in particle physics! Their violation would be a sign of new physics.

Feynman Diagrams

A powerful tool to visually represent particle interactions, as well as to conduct elaborate calculations! Learn the basics on how to read Feynman diagrams.

The Standard Model

All fundamental particles classified based on their properties! Deviations to the Standard Model can point the way to new physics.
