LHC physics data-taking gets underway at a new record collision energy of 8TeV. The LHC declares "stable beams" as two 4 TeV proton beams are brought into collision at the LHC’s four interaction points. This signals the start of physics data-taking by the LHC experiments for 2012. The collision energy of 8 TeV is a new world record, and increases the machine’s discovery potential considerably.
