ENGAC TeamThe four main LHC experimentsAcceleratorsCERN-AC-9906026This diagram shows the locations of the four main experiments (ALICE, ATLAS, CMS and LHCb) that will take place at the LHC. Located between 50 m and 150 m underground, huge caverns have been excavated to house the giant detectors. The SPS, the final link in the pre-acceleration chain, and its connection tunnels to the LHC are also shown.1999http://cds.cern.ch/record/40525http://cds.cern.ch/record/40525oai:cds.cern.ch:40525
