Another important milestone was achieved in the LHC beam commissioning: on 21 April, the LHC Engineer in Charge declared “stable beams” at 6.8 TeV, the first time in 2023

Following the winter shutdown, the injectors and accelerators are preparing for the 2023 data-taking season

With the progressive recommissioning of the injectors – including, now, the SPS – the various types of beam are being set up and are gradually reaching the downstream accelerators

The last LHC beam of 2022 was dumped in the early morning of Monday, 28 November; 17 weeks later, on Monday, 27 March 2023, we plan to inject the first beam of the year into the LHC

The first phase involves a major geographical, geological and environmental data-gathering effort

The first Chamonix workshop, dedicated to LEP performance, took place in 1991 – we’ve come a long way since then!

The first “MKI-Cool” was installed in early January – water-cooled ferrite cylinders will protect the LHC’s kicker magnets from increased heat load in the high-luminosity era

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

An LHC quadrupole whose beam screen had been coated with a fine layer of carbon displayed minimal heat load in comparison to other magnets, constituting a promising step in eliminating electron clouds in future particle accelerators

On 10 September 2008, the LHC circulated its first beams. It may not have been all plain sailing from then on, but the adventure had begun.
