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.

Take a tour through a truly historic building, which currently houses one of the major upgrade projects of the ATLAS collaboration: the New Small Wheels. Take a look at detector and prototype exhibits, witness the ongoing construction of the New Small Wheels, each nine meters in diameter, and learn about what it takes to build and run a particle-physics experiment the size of an apartment building.

Join the ATLAS main activity tent and learn all about the ATLAS experiment. Find out how ATLAS studies the Higgs boson; learn what protons are made of and how they collide inside the ATLAS detector; and uncover how ATLAS analyses particle collisions to make new discoveries. Take home a photo of yourself as an ATLAS scientist, sit down for a cup of coffee at our science café and chat with an ATLAS "barista" (physicist).

Take a tour of the ATLAS Visitor Centre. Learn about the experiment, take a peek at the ATLAS control room, and see the original prototype pieces of the detector pieces in the exhibition.

Discover an emerging acceleration technology that has the potential to drastically reduce the size, and thus the cost, of accelerators in the next several decades.

Imagine looking for an object 10 times thinner than a human hair that's moving close to the speed of light in a tunnel 100 metres underground. That's what beam experts at CERN do, monitoring the particle beams that travel in CERN's accelerators. Find out how they monitor the beams and try to play with a virtual beam yourself.

Come and discover the cutting-edge devices used to protect equipment and people from the huge amount of energy carried by the particle beams that are accelerated at CERN. Experts are on hand to explain the technical challenges of the design, fabrication and operation of absorbers, collimators and targets.

At this visit point you'll be able to see an old and a new radio-frequency system for particle acceleration in the Proton Synchrotron Booster machine and learn about particle-acceleration techniques that are adopted in synchrotron accelerators.

Come here to build and operate a detector that uses evaporated alcohol to make a "cloud" that can sense passing particles.

Plastic scintillator detectors give off light when hit by a particle. Come here to help assemble a small plastic scintillator detector and see it working. You'll also be able to see a replica of the scintillator detector that will be installed in the T2K neutrino experiment that is based in Japan.
