CERN's Large Hadron Collider begins major upgrade with Long Shutdown 3

The Large Hadron Collider (LHC) at CERN has been switched off to commence Long Shutdown 3 (LS3), an extensive period of maintenance, consolidation, and installation work. This multi-year upgrade program will prepare the world's most powerful particle accelerator for the High-Luminosity Large Hadron Collider (HiLumi LHC), which is scheduled to begin operations in 2030. The HiLumi LHC aims to increase the collider's luminosity by up to ten times, enabling researchers to collect significantly more data for new discoveries.
