Geneva, 20 November 2009. Particle beams are once again circulating in the worlds most powerful particle accelerator, CERN’s Large Hadron Collider (LHC). This news comes after the machine was handed over for operation on Wednesday morning. A clockwise circulating beam was established at ten o’clock this evening. This is an important milestone on the road towards first physics at the LHC, expected in 2010.
