The High-Luminosity Large Hadron Collider (HL-LHC):  the future of the LHC

CERN’s Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It has operated successfully since 2008 and at very high energy (13 TeV) since 2015. The data collected allowed the ATLAS and CMS experiments to discover the Higgs boson after decades of research.

The High-Luminosity Large Hadron Collider (HL-LHC) project aims to crank up the performance of the LHC in order to increase the potential for discoveries after 2025. To allow all these improvements to be carried out, major civil-engineering work at two main sites is needed, in Switzerland and in France.

• What are the stages of the project?
• Where and how will the construction works take place?
• What research will be conducted?

CERN scientists will meet their neighbours to present the project and answer questions at two public conferences held in neighboring municipalities:
- Cessy: Tuesday 9 October, 2018 at 20:00, Vidolet complex
- Prevessin-Moëns: Thursday 11 October, 2018 at 20:00, ALICE school
(A date is yet to be defined for Ferney-Voltaire)
