The Passport to the Big Bang is an interactive circuit through which you can explore this giant machine.


   Passeport Big Bang-plan    Passeport Big Bang-mission    Passeport Big Bang-info bulle    Plate-forme derrière Leclerc

Destination: the Universe, immediate departure


The Passport is available in tourist offices and town halls in the Pays de Gex and the Canton of Geneva, as well as from the CERN Reception, or  just here.

 Passeport Big Bang-signalétique

The cycle routes allow you to complete a circuit of the LHC at ground level, by passing from one platform to the next. The whole circuit is 54 km. The distances between two stages are an average of 4 km or about 30 minutes (each way). Signs only indicate the outward journey – bring a map, and check the maps at each stage for suggestions for the return route. The platforms are open to free public access



10 routes, 10 stages, 10 personal activation codes!
Your mission: the Large Hadron Collider has stopped working. You are needed to get it running again!



CCC Stage, Prévessin-Moëns: At the controls of the accelerators
In the CERN Control Centre, 24 hours a day operators work in shifts to control a network of particle accelerators like no other in the world.

Neutrinos Stage, Prévessin-Moëns: The journey of the phantom particles
The physicists working on the CNGS experiment have managed to improve their understanding of the elusive and mysterious neutrinos. How? By shooting them off on a super-fast journey through the Alps.

ALICE Stage, Sergy / St-Genis-Pouilly: In ALICE's Wonderland
Going underground and finding yourself at the very start of the history of our Universe... A dream? No. The daily life of physicists at the ALICE experiment.

Acceleration Stage, Echenevex  When energy creates matter
What passes under your feet over 11,000 times per second? The particles in the LHC!

CMS Stage, Cessy : CMS, the heavyweight of physics
CMS: does it stand for Concentration of a Mass of Science? No, but it could do, as this experiment is looking for the Higgs boson, the particle which gives particles their mass.

Environnement Stage, Versonnex: 10 questions about the LHC
A unique machine like the LHC inspires lots of questions. Separate the truth from all the rumours.

Cryogenics, Ornex  Cryogenics: the ice genie
Another amazing fact about the LHC? It's also the biggest and most powerful freezer in the world.

LHCb Stage, Ferney-Voltaire: The explorers of antimatter
Something unsuspected about physicists: they are obsessed with beauty. To explain more about the enigmas of antimatter, they are hunting for what we call beauty particles.

Precision Stage, Meyrin (CH): Scientific giants, devilish precision
The huge research instruments at CERN need to achieve outstanding precision and also need experts who measure up to them.

ATLAS Stage, Meyrin (CH): ATLAS, the colossus of physics
What is our Universe really made of? What is dark matter? Do hidden dimensions exist? These are some of the questions which the physicists at ATLAS hope to answer with their enormous underground experiment.
