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

Two cold boxes have been transported down into the service tunnels of the future accelerator

Now operational, a new heat exchange system is reusing hot water from part of the Large Hadron Collider’s cooling system to heat homes and businesses in the local area

The first large refrigerators for the High-Luminosity LHC have been installed

The delivery of two huge compressors kicks off the installation of the new helium refrigerators for the High-Luminosity LHC

The proton physics run has now been paused for the first block of machine development studies, a technical stop and short oxygen- and neon-ion physics runs. Protons will be back in the machines on 12 July

On 23 September, the LHC reached its 2024 target for integrated luminosity. And then a cryogenic station broke down…

The summer is often a very productive period for physics in CERN’s accelerator complex, that is, when the weather remains reasonable…

Four large helium tanks will supply the new High-Luminosity LHC refrigerators

CERN’s accelerators show very good availability rates: beams are in place

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

The new HL-LHC cold powering system, which includes the high-temperature superconducting link colloquially known as “the python”, has successfully passed its first cold powering tests
