CERN will announce tomorrow that the Large Hadron Collider (LHC) the largest and most powerful particle accelerator in the world, will start up its second three-year run. After substantial repairs and improvements over the last two years, the 27km (16.77 miles) long LHC will restart at a higher energy. The energy of particle collisions will be 13 TeV (or 6.5 TeV per beam) compared to 8 TeV (4 TeV per beam) in 2012. This higher energy will allow physicists to extend their searches for new particles and to check previously untestable theories. REUTERS/Denis Balibouse (FRANCE - Tags: SCIENCE TECHNOLOGY SOCIETY)

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)
