CERN's Large Hadron Collider Begins Major Upgrade Phase

CERN's Large Hadron Collider (LHC) began its Long Shutdown 3 (LS3) on June 29, 2026, for a significant upgrade. This program will convert the LHC into the High-Luminosity LHC (HL-LHC), aiming to increase its luminosity by up to ten times. The HL-LHC is projected to commence full scientific operation in 2030, facilitating more precise Higgs boson studies and potentially uncovering new physics.
