LHC-The Accelerator for the 21st Century

The LHC will take over from LEP in 2005. This new generation of particle collider will allow some 5000 physicists from all over the world to study the mysteries of matter and let them "see" back to the start of the Universe.

R&D phase: 1985-1995
Construction Period: 1995-2005
Running: 2005>2020

The extensive use of state-of-the-art technologies such as superconductivity has allowed a considerable increase in performance while at the same time reducing the power consumption.

The LHC test String.

The LHC makes maximum use of the LEP tunnel and CERN's existing accelerator complex.

The LHC will be housed in the LEP tunnel (27 km in circumference and 100 metres underground) which sits astride the Franco-Swiss border close to Geneva.

The two beams of protons or heavy ions go in opposite directions inside two ultra-high vacuum tubes which cross at four places. It is at these intersection points that the detectors of the experiments, ATLAS, ALICE CMS and LHCb will observe collisions.

The LHC represents 5000 man years of engineering effort from CERN and its collaborating institutes.
