High-Luminosity LHC upgrade work has begun at CERN after the Large Hadron Collider logged its final collision on June 27, 2026, entering a four-year, $1.5 billion Long Shutdown 3 program to replace 1.

LHC Run 3 began in 2022, with the recommissioning of the LHC at 6.8 TeV, resulting in the delivery of 39.7 fb⁻¹ of integrated luminosity, surpassing initial expectations. Luminosity is an important ...
