CERN’s physics programme ranges from nuclear to high-energy physics and from studies of antimatter to the possible effects of cosmic rays on clouds.

Particle accelerators propel sub-atomic particles to extremely high velocities for a variety of uses from high-energy physics research to medical scans and treatments.

Diverse experiments at CERN investigate physics from the early universe to supersymmetry.

Engineers at CERN build and test the machines and systems that physicists rely on, and technicians keep these systems running smoothly, performing repairs and upgrades where necessary.

Experiments at CERN generate colossal amounts of data. The Data Centre stores these data sets and sends them around the world for analysis.
