LHC 2008 - Open Day

2008 Open Day - Take a plunge into the wonderful world of the LHC

The world's largest particle accelerator lies 100 metres down, right under your feet… here is your one and only opportunity to discover it…

In 2008 CERN (the European Organization for Nuclear Research) will commission its Large Hadron Collider. The LHC, the world's most powerful particle accelerator, measuring 27 kilometres in circumference, will bring advances in our knowledge of matter and the Universe. The LHC will accelerate minute particles and collide them at the centre of four large detectors, ALICE, ATLAS, CMS and LHCb. The LHC is an exceptional scientific tool employing state-of-the-art technology to further fundamental science. It comprises over 1800 superconducting magnet assemblies, for example, and is maintained at a temperature of -271.3°C, just 1.9 degrees above absolute zero. The four experiments that will study the particle collisions are technological triumphs in themselves, the largest of them as tall as a five-storey building.

On Sunday 6 April 2008 CERN will throw open all the doors to the LHC. A range of exciting activities will be organised around the ring, both on the surface and underground.

“Globe Show” for the Open Day will be on satellite!

A diverse programme of visits to the laboratories on the surface and down to the tunnels and experiment caverns, as well as fun activities and workshops for young and old, demonstrations of superconductivity, lectures by Nobel Prize-winners and lots of other surprises await you at the sites in Meyrin (Switzerland) and Prévessin (France) and at all the access points around the ring!

The Open Day will kick off at 9.00 a.m. and continue until 7.00 p.m.
We look forward to seeing you at your nearest LHC point!

Please note that the number of visitors underground cannot exceed the maximum limit of 15000 at all points throughout the day.
