As the LHC and SPS wrap up their 2024 proton run, teams are making final preparations for the lead-ion physics run starting on 4 November

This year’s LHC proton run ended on 16 October, surpassing expectations with 11% more collisions than planned. Next up: the lead-ion run

On 23 September, the LHC reached its 2024 target for integrated luminosity. And then a cryogenic station broke down…

The physics run for the SPS North Area will start on 4 November, followed by the LHC lead-ion physics run on 6 November, and the PS East Area on 11 November

On Sunday, 1 September, the LHC integrated luminosity for Run 3 (2022–2025) equalled that of Run 2 (2015–2018)

The summer is often a very productive period for physics in CERN’s accelerator complex, that is, when the weather remains reasonable…

CERN’s accelerators show very good availability rates: beams are in place

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

We are optimistic that we will have a successful luminosity production period this summer

The LHC injector chain has been switched to a new beam production scheme to explore its potential to produce more collisions in the LHC and to compare its performance to that of the standard LHC beam

The LHC is performing well and the injector complex is treating its experimental users to a high level of beam availability

In the last two weeks, the LHC teams have encountered two main challenges that have led to some changes to the filling scheme
