Contact: ALICE visits for scheduling a visit!

ALICE is one of the four large experiments at the CERN Large Hadron Collider (LHC). It is situated at Point 2 of the LHC, on the border of Saint-Genis Pouilly and Sergy in France, just 2.5 km from the CERN visitor center in Meyrin, Geneva. 

The ALICE detector weighs 10000 tonnes and is 26 meters long, 16 meters high, and 16 m wide. It sits in a vast cavern 56 meters below ground.  ALICE is designed to study the physics of strongly interacting matter at extreme conditions of temperatures and energy densities, where a phase of matter called the quark-gluon plasma (QGP) forms.

Have you ever dreamed of visiting a large-scale physics experiment?
Then you are at the right place :)  Be part of a journey of discovery!

On-site in-person visits: The best possible way to explore and experience the experiment is to have the opportunity to visit ALICE in person. While there, you will see the ALICE exhibition, ALICE Run Control Centre, and the underground cavern where the detector is located (depending on the access situation). Yes, the underground cavern remains inaccessible during beam operations (check the underground access condition here).

Virtual visits:  Virtual visits of ALICE are possible for remote audiences. Virtual visits are organized standalone or in combination with local events. To book a virtual visit, contact the ALICE outreach team at the e-mail address: alice-outreach-virtual-visits


ALICE exhibition

Here we first watch an introductory film projected on a real-size mockup of the detector. The film is available in 12 languages and is aimed at the general public without prior knowledge of particle physics. Starting from introducing the quarks and gluons, it explains the origin of the universe and the physics of heavy-ion collisions. It then talks about the ALICE experiment, used as a tool to study the quark-gluon plasma.

ALICE underground

The cavern of the ALICE experiment - is a 50 m high dome, located 50 m underground. The solenoid magnet inherited from the former LEP experiment L3 is the most spectacular component of the experiment.


ALICE Run Control Centre (ARC)

The ALICE Run Control Centre (ARC) is at the heart of all ALICE operations. ALICE Run coordination team is responsible for the smooth operation of all the detectors and coordination with the CERN control center (CCC). ALICE collaborators take part in the detector shifts which occur 24 hours a day, seven days a week. Large screens mounted on the walls display the status of the beam from the LHC, the status of detectors, and some beautiful event displays.
