Work for the High-Luminosity LHC is in progress right under our feet

A 1000+ page report quantifies the physics potential of the High-Luminosity Large Hadron Collider

After years of careful preparation, the LHC’s second long shutdown, LS2, is now under way. Over the coming 18 months, the upgrade of the LHC’s injector complex will be the primary focus for technical teams across the Organization

With the LHC switched off for a two-year technical stop, CMS is undergoing significant maintenance and upgrades

Enhancing ATLAS’s detection capabilities in preparation for the LHC restart

Major internal improvements await the ALICE detector during CERN’s Long Shutdown 2 (LS2)

Excavation of the two new shafts for the HL-LHC at points 1 and 5 of the accelerator has been completed

Tests carried out in 2018 on two crab cavities in the SPS validated their technical principle and many operating parameters

The beam screen for the High-Luminosity LHC will be installed by 2024 in the aperture of the inner triplet superconducting magnets near ATLAS and CMS

After an outstanding performance, the Large Hadron Collider (LHC), the accelerator complex and the experiments are now stopping for two years for major improvements and upgrading.
