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 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

On Friday, 30 June, an exciting milestone was reached: the much-awaited antiproton physics season finally commenced

The AD operations team received on Friday, 1 June – 12 days earlier than rescheduled – the green light from the AD injection kicker expert: beam could be injected again in the AD ring

On 11 May, four days before the original schedule had set a target of 1200 bunches per beam, the LHC made its final intensity ramp-up step to 2400 bunches per beam

Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes

Looking back on an exciting year for the LHC and its injector complex

Both the CMS and ATLAS experiments have performed luminosity measurements with spectacular precision

The LHC’s 2017 proton run has ended with record luminosity. The special runs will now take place before the winter shutdown.
