High Luminosity Large Hadron Collider HL-LHC

Understand

HL-LHC federates the efforts and R&D of a large international community towards the ambitious HL- LHC objectives and contributes to establishing the European Research Area (ERA) as a focal point of global research cooperation and a leader in frontier knowledge and technologies.

• HL-LHC relies on strong participation from various partners, in particular from leading US and Japanese laboratories.
• This participation will be required for the execution of the construction phase as a global project.
• In particular, the US LHC Accelerator R&D Program (LARP) has developed some of the key technologies for the HL-LHC, such as the large-aperture niobium-tin ($Nb_{3}Sn) quadrupoles and the crab cavities.
