Discover the technologies that underpin the Compact Muon Solenoid (CMS) detector and its subdetectors.

Code of the Universe is a travelling photographic exhibition that captures worldwide collaborative efforts to understand the universe and how these efforts have led to an array of scientific and technological breakthroughs. Come here to see part of the exhibition. The full exhibition can be seen at https://codeoftheuniverse.web.cern.ch.

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.

Did you know that you can detect a material without touching it by measuring its electrical properties? Get a live demonstration of how changes in electrical capacitance can be used to detect movements of your hand, to count sheets of paper and much more than this in the context of particle accelerators.

Come to this visit point to explore the cryogenic systems used to cool down to -271.35 Celsius all the superconducting magnets. They keep particle beams on course around the LHC's 27-kilometre ring.

Come and discover the particularities of cryogenic liquids and the fascinating properties of matter at low temperatures. You'll also have a chance to taste an excellent ice cream made with liquid nitrogen.

Scintillating crystals give off light when hit by a particle. Find out how they are used in particle-physics experiments, such as CERN's CMS experiment, and in medical imaging.

How will the future be shaped by new trends? Come and discuss our shared future in a programme of talks and debates interspersed with comedy, theatre and music. You will hear CERN's Director-General, Fabiola Gianotti, and the head of the CERN Theory group, Gian Giudice, give a glimpse into questions for the future. The head of the LHC's high-luminosity upgrade, Lucio Rossi, will share his enthusiasm for the luminous future of the LHC. Expand your horizons with debates on future intelligence, open science and arts and science collaborations. Enjoy a bit of music with an excerpt of the opera Einstein on the Beach by the Grand Théâtre de Genève and a short performance by world-renowned jazz musician Vladimir Tarasov.

Circuit through the two main data rooms in the CERN Data Centre. Additional activities include watching a video about the creation and development of the Web and the issues it faces today, learning how the avalanche of data produced by the physics experiments is stored, distributed and processed, and attending short talks on a variety of information-technology topics.

The TE-MPE-EM section provides centralised services for CERN's electronics community, offering design services, prototype board assembly, and production of electronic circuit boards and modules. In our workshop, you can see the machines and processes used to produce modern electronics, from particle-accelerator parts to personal computers.
