Cern: Tunnel driving has begun

The particle accelerator LHC, the Large Hadron Collider of Cern, is being expanded. The HiLumi-LHC project is scheduled to go into operation at the end of 2025. In essence, the number of proton collisions is to increase from one billion collisions per second to five billion. The researchers at Cern are looking for unknown elementary particles to explain previously unsolved secrets of the universe. One of the groundbreaking discoveries was the detection of the Higgs Boson.

More space for research

To achieve this, a large amount of infrastructure and underground space is required. New tunnels and a large cavern are being built, as wells as above-ground auxiliary buildings.

Electric tunnel excavator

Excavation work for the shaft began at the beginning of August. A tunnel excavator specially converted from diesel to electricity by Marti Tunnel will progress half a metre a day to a depth of 60 metres until the end of 2018. The cavern and the connecting tunnels to the particle accelerator will then be built.
