Number 208 (Story #1), December 22, 1994 by Phillip F. Schewe and Ben Stein THE CERN COUNCIL HAS APPROVED THE CONSTRUCTION OF THE LARGE HADRON COLLIDER (LHC). The huge proton-proton collider, to be housed in the existing 27- km tunnel used by the Large Electron Positron collider, will be built in two stages. First, 5-TeV beams will be achieved by about the year 2004. Head-on collisions would have a total energy of 10 TeV. Primary topics of study in this first phase would be top quarks and CP violation. In the second phase, to start in 2008, the total collision energy would be boosted to 14 TeV. At this energy the search for the Higgs boson would be a high priority. Financial investments by non- member states such as the U.S., Russia, and Japan, would influence the rate at which construction would proceed.
