# LHC physics underway at record collision energy of 8TeV

At 12.38pm CEST this morning, the LHC shift crew declared "stable beams"

At 12.38pm 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. 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.
