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

In the last two weeks, the LHC teams have encountered two main challenges that have led to some changes to the filling scheme

Following the completion of a successful in-house development phase, CERN is equipping the ATLAS and CMS detectors with new carbon dioxide (CO2) cooling systems that will contribute to the transition towards green and sustainable technology in this area

Despite challenging working conditions, the vacuum leak caused by the quench that occurred on 17 July was repaired in less than 10 days

On Monday, 17 July, the LHC beams were dumped after only 9 minutes in collision due to a radiofrequency interlock caused by an electrical perturbation

A flexible cryostat and the first series of high-temperature superconducting magnesium diboride cables will form an innovative electrical transfer line to power the HL-LHC inner triplet magnets

SM18 is one of the largest magnet test facilities in the world. Dedicated to testing superconducting magnets and radiofrequency cavities, it is now waiting for the first HL-LHC components

CERN has strong partnerships and collaborations with laboratories and research infrastructures in the Member States. One recent example saw superconducting magnets for the future FAIR facility at Germany’s GSI laboratory being tested at CERN
