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

The ATLAS and CMS collaborations have joined forces to establish the first evidence of the rare decay of the Higgs boson into a Z boson and a photon

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

The beam commissioning of the Antiproton Decelerator will start on 12 June, and the aim is to deliver antiprotons to the eagerly waiting AD-ELENA experiments on 30 June

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!
