CERN-made HiLumi LHC quadrupoles ready for installation
After years of design, manufacturing and testing, the High-Luminosity (HiLumi) LHC magnet programme has reached a landmark point: all eight new CERN-made quadrupole magnets needed for installation are ready for the tunnel (with two spares produced and entering their final stages). Known as the new inner triplets, these magnets are now complete and have been fully

Accelerator Report: From protons to ions – the LHC and its injectors prepare for the Run 3 finale
At 6 a.m. on 19 May, the LHC Run 3 proton physics programme officially came to an end. Thanks to the excellent performance and availability of both the LHC and its injector chain, this year’s integrated luminosity surpassed all expectations, with all four main LHC experiments recording values well above the original projections (fig. 1).

Accelerator Report: The 2026 run will be short but intense
Every day counts, so the LHC operations teams have mapped out a precise sequence of running phases to maximise the physics output during the machine’s final months

Accelerator Report: 2025 is another record-breaking year for protons in the LHC
The 2025 LHC proton run has come to a close, with record performance delivered to all experiments. The LHC now gears up for the upcoming lead-ion run

Accelerator Report: When plans meet reality…
The two beams circulating in the LHC are currently running with different bunch intensities – an unexpected (but successful) premiere, giving us a good chance to reach last year’s luminosity record

Accelerator Report: We reached 100!
On 6 October, the total integrated luminosity passed the symbolic mark of 100 fb⁻¹, exceeding the forecast curve. This allowed the bunch intensity to be increased to explore the intensity reach and limitations in view of the HL-LHC era

Accelerator Report: LHC performance stays on track and is cruising towards the target
As the 2025 LHC run enters its final ten weeks, strong performance pushes luminosity past 90 inverse femtobarns, while lead-ion preparations are ahead of schedule

Accelerator Report: The LHC wraps up its first 2025 physics block
The proton physics run has now been paused for the first block of machine development studies, a technical stop and short oxygen- and neon-ion physics runs. Protons will be back in the machines on 12 July

Accelerator Report: LHC protons outpacing the Easter tradition
The LHC has restarted and both beams have been circulating in the machine since 8 April, meaning that the start of the LHC beam commissioning during Easter is apparently not a constant of nature
