Underground electrical connection between LHC Points 6 (Versonnex) and 5 (Cessy)

In preparation for the High-Luminosity LHC, CERN will construct an underground electrical connection between LHC Points 6 (Versonnex) and 5 (Cessy) in 2024

2024 - 2025

The High-Luminosity LHC (HL-LHC)

The High-Luminosity LHC project will allow the LHC to be exploited to its full potential.

2018 - 2029

Mind where you bore!

The presence of the LHC’s underground installations around the French-Swiss border results in a number of limitations regarding boring for geothermal probes.
