CERN‘s Large Hadron Collider stops for two years of maintenance and tune-ups, after three-year running period with major advances in physics, including the discovery of the ‘God particle’, the Higgs boson, announced on 4 July 2012.

“We have every reason to be very satisfied with the LHC’s first three years,” said CERN Director-General Rolf Heuer. “The machine, the experiments, the computing facilities and all infrastructures behaved brilliantly, and we have a major scientific discovery in our pocket.”
The LHC now begins its first long shutdown, LS1. Over the coming months major consolidation and maintenance work will be carried out across the whole of CERN’s accelerator chain. The LHC will be readied for higher energy running, and the experiments will undergo essential maintenance. LHC running is scheduled to resume in 2015, with the rest of the CERN complex starting up again in the second half of 2014.
“There is a great deal of consolidation work to do on CERN’s whole accelerator complex, as well as the LHC itself,” said CERN’s Director for Accelerators and Technology, Steve Myers. “We’ll essentially be rebuilding the interconnections between LHC magnets, so when we resume running in 2015, we will be able to operate the machine at its design energy of 7TeV per beam”.
