CERN's Large Hadron Collider Begins Major Upgrade Phase

The Large Hadron Collider (LHC) at CERN has been switched off to commence Long Shutdown 3, a significant upgrade program aimed at transforming it into the High-Luminosity Large Hadron Collider (HL-LHC). This multi-year effort involves replacing major components, modernizing experimental facilities, and carrying out infrastructure upgrades to dramatically improve the accelerator's performance and increase the number of particle collisions for future scientific operations.
