Organising and coordinating activities during LS3: a shared responsibility
LS3 is set to be a busy period for CERN, with a wide range of activities taking place across the accelerators, experiments and buildings on the site – from construction, maintenance and upgrades, to consolidation and installation work, transport operations, tests and more. When these interventions overlap, the risks associated with concurrent activities increase. To

Accelerator Report: An important upgrade to the PS radiofrequency system and a heavy ion run in full swing
In a particle accelerator, radiofrequency (RF) systems are among the crucial components that make beam production possible. While magnets guide the particles around the ring, RF systems provide the beam with its longitudinal structure: they accelerate it, keep it captured in bunches, shape it, split it, rotate it and ensure synchronisation for transfer to the

LS3 Safety Spotlight: be road safe
As CERN prepares for LS3, road safety – one of the nine newly approved CERN Safety Fundamentals – is more critical than ever. Increased traffic, movement of equipment and a higher density of people and vehicles across the site raise the risk of accidents. In 2024 and 2025, there were 210 reported road safety incidents

Save the date! CERN Safety Day – 4 June: keeping ourselves and each other safe
Every day at CERN, we all face a variety of risks, from potential trips and falls to activity-specific hazards. Safety starts with you. On 4 June, join the HSE Department and collaborating teams at Restaurant 1 and in the Main Building for an interactive CERN Safety Day. Discover hands-on demonstrations on many topics, spanning electrical

HiLumi LHC: CERN’s full-scale test stand enters the powering phase
With the start of electrical powering, the Inner Triplet String is now entering a new phase of commissioning. This phase will be carried out progressively and will culminate in the powering of the whole installation this summer

Accelerator Report: The accelerator complex is gradually waking up from the winter shutdown
Beam commissioning is progressing well in CERN’s accelerator complex, with beams already at the gates of the SPS

Accelerator Report: A very busy technical stop ahead of Long Shutdown 3
This technical stop is particularly intense, being both shorter than usual, to maximise the limited time for physics, and very busy, to make essential preparations for LS3, which begins in June

New schedule for CERN’s accelerators
The LHC’s third run has been extended until July 2026. The long technical stop that will follow will be extended by four months, postponing the start-up of the High-Luminosity LHC until June 2030

Updated schedule for CERN’s accelerators
The timing and duration of the third long shutdown (LS3) of the Large Hadron Collider and injector complex has changed, here’s why
