The Large Hadron Collider LHC

The Large Hadron Collider Project LHC was approved by the CERN Council in December 1994. Commissioning with beam will start in the second half of 2005. The paper discusses the most important parameters, the general layout of the LHC octants, the status of the experiments ALICE, ATLAS, CMS and LHC-B, proton injection using the PS booster, and the proton synchrotrons PS and SPS. Also described are the technical developments of the arc dipoles, the radio-frequency system, the vacuum chamber, cryogenics and the tests of half an arc cell.
