Large Hadron Collider to Undergo Major High-Luminosity Upgrade | Quick Digest
The Large Hadron Collider (LHC) is scheduled for a multi-year shutdown beginning in September 2026 for a significant upgrade to transform it into the High-Luminosity LHC (HL-LHC), with operations expected to resume around mid-2030. This upgrade aims to boost its collision capacity tenfold.

LHC to begin Long Shutdown 3 (LS3) in September 2026 for upgrades.

The shutdown is for the High-Luminosity LHC (HL-LHC) project.

Upgrade will increase collision intensity tenfold for more data.

LHC operations are expected to resume around mid-2030.

CERN is also planning the LHC's successor, the Future Circular Collider (FCC).

The initial Futurism headline was partially accurate but sensationalized.

The Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator located at CERN near the Swiss-French border, is indeed scheduled for a significant, multi-year shutdown, but not a permanent one. The article's headline from Futurism, 'The Large Hadron Collider Is Being Shut Down,' is partially accurate but sensationalized, as it is a planned temporary closure for a major upgrade rather than a cessation of operations. CERN's current operational phase, known as Run 3, is set to conclude in July 2026. Following this, the LHC will enter its third Long Shutdown (LS3), starting in September 2026, which is anticipated to last for several years. This extensive downtime is dedicated to upgrading the accelerator to the High-Luminosity Large Hadron Collider (HL-LHC). The HL-LHC project aims to dramatically increase the number of particle collisions by a factor of ten, allowing scientists to gather far more data and conduct a wider range of experiments to probe deeper into the fundamental mysteries of the universe. Engineers will install new superconducting magnets and enhance various components of the accelerator complex and its detectors during this period. The HL-LHC is expected to become operational again around mid-2030. Mark Thomson, the new Director-General of CERN as of January 2026, will oversee this significant upgrade period. Beyond the HL-LHC, CERN is also actively planning for a potential successor, the Future Circular Collider (FCC), which could be a much larger machine and potentially operational in the mid-2040s, succeeding the LHC programme around 2041. This planned shutdown is a crucial step in advancing particle physics research globally.
