CERN Shuts Down Large Hadron Collider for Major Upgrade Until 2030

CERN has powered down the Large Hadron Collider (LHC), the world's largest particle accelerator, to begin its most extensive overhaul to date, known as Long Shutdown 3 (LS3). The upgrade involves replacing 1.2 kilometres of magnets as part of the transition to the High-Luminosity LHC. Once completed, the upgraded machine is expected to increase collision rates tenfold compared to current levels. The revamped collider is scheduled to resume operations around 2028 and reach full functionality by 2030.
