Notable
**CERN has not been shut down; only the Large Hadron Collider (LHC) was permanently powered off on June 29, 2026, following its final physics run.
The LHC is undergoing a planned four-year upgrade called Long Shutdown 3 (LS3) to transform it into the High-Luminosity LHC (HiLumi LHC). This massive engineering project involves replacing 1.2 kilometers of magnets and components to increase collision luminosity by a factor of ten. The upgraded collider is scheduled to restart operations in 2030, while CERN continues to operate other facilities and analyze existing data during this period.
CERN bids farewell to the LHC and enters Long Shutdown 3
The Large Hadron Collider is embarking on its most ambitious upgrade yet
29 June, 2026
While no particle beams will circulate during this period, CERN’s scientific activity will remain intense. Thousands of researchers will continue analysing the vast datasets accumulated during the LHC era, extracting new physics results while simultaneously preparing the experiments for the challenges ahead.
When the accelerator complex gradually restarts, from 2028, it will inaugurate a new era for high-energy physics. Building on the legacy of the LHC, the HiLumi LHC will provide unprecedented opportunities to deepen our understanding of the Universe and explore some of the most fundamental questions in science.
