HiLumi LHC: new magnets reach full power
The test bench for the High-Luminosity LHC, the IT (Inner Triplet) String facility, has reached a major milestone. On 8 July, its new quadrupole magnets – known as the inner triplet magnets – successfully reached their nominal operating current of 16 230 amperes. Designed to focus the beams more tightly than ever before, thereby increasing the

Efficiency meets environmental responsibility: commissioning CERN’s primary CO₂ cooling circuit
The ATLAS and CMS detectors require ultra-low, stable temperatures to protect their sensitive electronics. Traditional cooling systems rely on synthetic refrigerants like hydrofluorocarbons (HFCs), which, while effective, have a global warming potential thousands of times greater than CO₂. Seeking a sustainable alternative, CERN has turned to CO₂ itself – a natural refrigerant with a far

Accelerator Report: Pushing the LHC towards HiLumi LHC conditions… and cut!
The final weeks of Run 3 for the LHC have been among the busiest of its entire operational period. With physics production successfully completed on 14 June, the machine entered a two-week programme dedicated to studies with high-intensity beams, followed by a quench campaign. These activities were scheduled after the completion of the physics programme

CERN bids farewell to the LHC and enters Long Shutdown 3
Today, the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, comes to the end of an extraordinary chapter in its scientific journey. Following its final physics run, the accelerator has been switched off to begin CERN’s Long Shutdown 3 (LS3), a major programme of maintenance, consolidation, upgrades and installation work that will prepare the

CERN begins beryllium beam-pipe production
Supported by CERN and the LHC experiment collaborations, the workshop will construct essential components for HiLumi LHC and future particle physics experiments

Final collisions, new horizons
In the early hours of Sunday, 14 June, the experiments at the Large Hadron Collider (LHC) had their last hurrah. In the control rooms of ALICE, ATLAS, CMS and LHCb – the four major experiments at the accelerator – scientists watched the final collisions burst across their screens like colourful fireworks. The collisions for physics

LHC season finale, up next… HiLumi
Join scientists in the CERN Control Centre as the Large Hadron Collider (LHC) delivers its last collisions to its experiments before it is transformed into a high luminosity machine. Host Davide De Biasio will guide you through the journey of the world’s most powerful particle collider through conversations with the Head of LHC Operations, the

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

Cloudy with a chance of muons
When you want to capture an important moment in your life, you often take a photo. You could write down the key details instead – who you were with, where you were, the time of day – but this information might not be as impactful as a picture of the event. Physicists like to record

Smarter decisions at the speed of physics
Smart and fast decision making is key when dealing with the onslaught of collisions at the LHC. At the High-Luminosity LHC (HiLumi LHC), the ATLAS and CMS experiments are expected to process detector data at rates corresponding to roughly a quarter of the 2025 global internet traffic. All in real time, as part of the
