CERN NEWS: A Long Shutdown for the LHC

On 14 February at 7.24 am, the shift crew in the CERN Control Centre extracted the beams from the Large Hadron Collider (LHC), bringing the machine's first three-year running period to a successful conclusion. 8 TeV collision energy was enough to find a new particle, but that's not the maximum energy the LHC was designed for.
For the LHC to reach its nominal energy of 14 TeV, extra work is now needed.
