CERN's Large Hadron Collider Enters Major Upgrade Phase for High-Luminosity Era

The Large Hadron Collider (LHC) at CERN has officially concluded its operations to begin Long Shutdown 3 (LS3), a significant maintenance and upgrade program. This phase will prepare the world's most powerful particle accelerator for its successor, the High-Luminosity LHC (HiLumi LHC), which is expected to gradually restart from 2028 and achieve full scientific operation by 2030. The upgrade aims to dramatically increase the LHC's performance, offering unprecedented opportunities to deepen the understanding of the universe.
