Technicians talks during the preparation of the beam in the Control Room of the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (CERN) near Geneva April 5, 2012. At 0:38 CEST this morning, the LHC shift crew declared "stable beams" as two 4 TeV proton beams were brought into collision at the LHC's four interaction points. The collision energy of 8 TeV is a new world record, and increases the machine's discovery potential considerably. REUTERS/Denis Balibouse (SWITZERLAND - Tags: SCIENCE TECHNOLOGY SOCIETY)
