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!

Discover the Alpha Magnetic Spectrometer (AMS), a multi-purpose magnetic spectrometer on the International Space Station (ISS) that measures cosmic-ray events up to teraelectronvolt energies. These events are analysed at the AMS Science Operations Centre located at CERN and at universities around the world.

This show will introduce you to the evolution of the (anti-)universe. By learning about atoms, anti-atoms and the scientific method, you will help to solve the mystery of antimatter.

Imagine looking for an object 10 times thinner than a human hair that's moving close to the speed of light in a tunnel 100 metres underground. That's what beam experts at CERN do, monitoring the particle beams that travel in CERN's accelerators. Find out how they monitor the beams and try to play with a virtual beam yourself.

Come here to build and operate a detector that uses evaporated alcohol to make a "cloud" that can sense passing particles.

Plastic scintillator detectors give off light when hit by a particle. Come here to help assemble a small plastic scintillator detector and see it working. You'll also be able to see a replica of the scintillator detector that will be installed in the T2K neutrino experiment that is based in Japan.

Come to this visit point to learn how to recognize and care for a person in cardiac arrest, through a playful and interactive race.

Discover the nerve centre from which the particles of the Large Hadron Collider (LHC) are controlled.

Head to the COMPASS building to see different aspects of a high-energy-physics experiment: the beam line, where the particle beam extracted from the Super Protron Synchrotron machine comes from, the target area, where the beam interacts with a target, and different types of particle detectors.

Come to the ENLIGHT (European Network for Light Hadron Therapy) stand to learn the basic principles of particle therapy, which is based on particle accelerators and is becoming increasingly important for the treatment of cancer.
