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

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

A High-Luminosity LHC instrument known as the Beam Gas Curtain will be tested and start collecting data during Run 3

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

In their first Run 3 results, the ATLAS collaboration measured two Standard Model processes: the production of Z bosons and top-quark pairs

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

CMS measured the top-quark pair production cross section

The subdetector aligned more closely with the LHC beam than ever before, marking an important milestone in LHCb data taking

This year, CERN celebrated the restart of the LHC, the beginning of the LHC Run 3 and the 10th anniversary of the Higgs boson discovery. These milestones contributed to a surge of interest in CERN and particle physics among the public.

LHCf has completed its first data-taking period during LHC Run 3, taking advantage of the record 13.6 TeV collision energy. This coincides with the machine’s record fill time of 57 hours

A round of applause broke out in the CERN Control Centre on 5 July at 4.47 p.m. CEST when the Large Hadron Collider (LHC) detectors started recording high-energy collisions at the unprecedented energy of 13.6 TeV
