Let yourself be enchanted!
The Compact Muon Solenoid (CMS) is the heaviest Experiment at the Large Hadron Collider (LHC) at CERN.
The LHC it's a ring of 27km that accelerates beams up to nearly the speed of light and collides them at specific locations: one of these is Point-5 in Cessy, France, and there you'll find CMS.
The CMS detector is like a giant photo camera located in a cavern 100m underground. It allows us to "see" what human eyes cannot: the world at its atomic scale.
CMS invites you to explore the fascinating world of particle physics and the beauty of the detector offering two kinds of visits. Choose the one that is better for you!
