Prévessin

CERN’s second-largest site, straddling the communes of Prévessin-Moëns and Saint-Genis-Pouilly, was constructed in the 1970s at the same time as the SPS accelerator – a 7-km ring that seemed huge at the time!

Marvel at these simple but entertaining experiments, often bordering on the magical, which demonstrate different states of matter and magnetism in a fun way.

Prévessin

Come and play the classic game "Guess Who?" but with the fundamental particles described by the Standard Model of particle physics.

Prévessin

Find out how surveyors align accelerators components with a high precision using sensors and adjustment systems.

Prévessin

Go inside the LHC-tunnel simulator, the place where new CERN staff learn the safety procedures for underground emergency evacuation.

Prévessin

Discover the NA61/SHINE experiment, which studies the properties of particles produced in collisions of protons, or other hadronic particles, with an assortment of fixed targets.

Prévessin

Discover the NA62 experiment, an experiment in CERN's North Area that directs particle beams onto fixed targets. The experiment aims to precisely test the Standard Model by looking for rare transformations of particles called charged kaons.

Prévessin

Discover the NA64 experiment and how it directs a proton beam from the Super Proton Synchrotron into a fixed target to search for an invisible form of matter called dark matter which makes up the most of the mass of the Universe.
