Almost the whole accelerator complex is now in “physics mode”, routinely delivering the various types of beam to the different physics facilities and experiments. Notably, the intensity ramp-up in the LHC is progressing remarkably well

This marks the beginning of physics for the third year of Run 3 of CERN’s flagship particle accelerator

The whopping number of collisions recorded by ALICE during the recent five-week heavy-ion run of the LHC is 40 times greater than the total recorded by the experiment in its previous periods of heavy-ion data taking, from 2010 to 2018

The year-end technical stop (YETS) officially started on 30 October, with promising performance tests in Linac4. The injection of the first 2024 LHC beam is scheduled for 11 March 2024

Another few days and the last 2023 LHC beams will be dumped, hopefully by the machine protection system following a controlled magnet quench

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
