From huge transformers to optical fibres the width of a human hair, see all the equipment used to supply CERN's accelerators and experiments - it's electrifying!

Get an introduction to the design and production of electronics for particle detectors and find out about the Medipix family of chips developed at CERN that has proved its credentials outside the field of high-energy physics, including in art authentication and restoration.

The current model of the universe cannot explain several things, such as the nature of dark matter and why is there no antimatter. Find out how a future particle collider could help search for answers to these questions.

The High-Luminosity LHC (HL-LHC) is a major upgrade of the LHC that aims to increase the number of particle collisions that occur each second and the amount of data that the experiments can gather and analyse. Come and discover the technologies that will make it possible.

Ride, run, or row along with live action videos on Kinomap. Have a virtual bike ride through the LHC during the CERN Open Days. Try to break the speed record or be faster than your friends or family.

Come and meet the CERN community. Find out how your country is represented at CERN, have a coffee with one of our scientists, and learn about the Future Circular Collider project and the Middle East's SESAME light-source facility, an example of science for peace in action. All this interspersed with listening to music performed by CERN scientists and staff members, or laughing at comedy by the Big Van Ciencia troupe from Barcelona. For those of you who have worked at CERN, see what the CERN Alumni Network has to offer and connect with the CERN Alumni Relations team.

The ISOLDE facility produces beams of exotic ions for studies of the structure of atomic nuclei and a variety of other purposes including medical applications. Discover the facility and get hands-on demonstrations of some of the techniques used to perform experiments at the facility.

Visit Linear Accelerator 2 (Linac 2), the starting point for the protons used in CERN's experiments. Here, you will learn how the machine creates protons in an ion source and accelerates them for further acceleration in other CERN machines.

Find out about the 86-metre-long linear accelerator that is scheduled to become the source of proton beams for the LHC from 2020, replacing the 37-metre-long Linear Accelerator 2 (Linac 2).

Discover the Low Energy Ion Ring (LEIR), which receives long bunches of ions from Linear Accelerator 3 (Linac 3) and transforms them into short, dense bunches that are suitable for acceleration in the chain of accelerators that feeds the LHC.
