Seven experiments at the Large Hadron Collider (LHC) use detectors to analyse the myriad of particles produced by collisions in the accelerator. These experiments are run by collaborations of scientists from institutes all over the world. Each experiment is distinct and characterised by its detectors.

Accelerator Report: Full house in the LHC
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

Giorgio Brianti (1930 – 2023)
Giorgio Brianti(1930 – 2023) — Giorgio Brianti, a pillar of CERN throughout his 40-year career, passed away on 6 April at the age of 92. He played a major role in the success of CERN and in particular the Large Electron–Positron Collider (LEP) project, and his legacy lives on across the whole of the accelerator

Accelerator Report: Crescendo at the LHC following the first stable beams at 6.8 TeV
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

Accelerator Report: Beam is back in the LHC
On Wednesday 22 March, the LHC machine, the injection beam lines and all the experiments were closed for the cold check-out of the LHC, an important phase in the commissioning that follows the hardware tests and is a prerequisite for injecting beam into the machine. During this phase, all safety and interlock systems are activated
