Visit the LHC tunnel and go inside the ALICE experiment, which recreates and studies a state of matter that is thought to have existed in the first moments of the universe. Back from this underground visit, you'll be able to meet ALICE physicists and engineers and take part in a range of activities.

Take a tour through the ATLAS underground cavern to see the largest detector ever built at a particle collider: the ATLAS experiment. Learn about the detector, the science and the collaboration.

Descend 100 metres underground and take a walk in the cathedral-sized cavern that houses the 14 000-tonne CMS detector - one of the two experiments that discovered the Higgs boson! The detector is located in the 27-km subterranean tunnel that contains the LHC - the world's largest scientific instrument!

Take a walk through the underground tunnel of the world's largest accelerator. Among the highlights, you will see the superconducting cavities that accelerate the particles in the LHC, the bending magnets of the machine and the cavern with radio-frequency equipment.

A proton beam circulating in the LHC can contain as much energy as a high-speed train travelling at 150 kilometres per hour, which needs to stay on track. How can we stop the beam and absorb this energy? Here you will explore the LHC 'beam dump' system.

Visit the underground LHCb experiment, which studies elementary particles known as heavy quarks to try and spot differences between the behaviour of matter and antimatter. Such studies might help explain why the universe is almost devoid of antimatter.
