At 8.25am the shift crew in the CERN Control Centre extract the beams from the Large Hadron Collider (LHC) for the last time before the machine's first Long Shutdown. The two-year shutdown will see a hive of maintenance activity on all of CERN's accelerators. Work on the LHC will include the consolidation of more than 10,000 interconnections between magnets. The entire ventilation system for the 628-metre circumference Proton Synchrotron will be replaced, as will over 100 kilometres of cables on the Super Proton Synchrotron. The LHC is scheduled to resume in 2015.
