HL LHC: High Luminosity Large Hadron Collider

The HiLumi LHC Design Study ran as an FP7 funded project between 2011 and 2015. The project now has moved from the design study to the machine construction phase. HL-LHC will extend the LHC’s discovery potential, increasing luminosity by a factor of 10 beyond the original design value and allowing the scientific community to study new phenomena.
