A second 7.2-metre-long HL-LHC triplet quadrupole has reached the currents needed for 7 TeV operation, with higher performances

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

The first Chamonix workshop, dedicated to LEP performance, took place in 1991 – we’ve come a long way since then!

The first “MKI-Cool” was installed in early January – water-cooled ferrite cylinders will protect the LHC’s kicker magnets from increased heat load in the high-luminosity era

The 7.2-metre-long version of this vital HL-LHC component reached nominal current plus an operational margin corresponding to a coil peak field of 11.5 T at 1.9 K during a test in SM18

CERN celebrates the completion of the civil-engineering work for the High-Luminosity LHC (HL-LHC), the major upgrade of its flagship collider, the LHC

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

An LHC quadrupole whose beam screen had been coated with a fine layer of carbon displayed minimal heat load in comparison to other magnets, constituting a promising step in eliminating electron clouds in future particle accelerators

The construction of the last surface buildings for HL-LHC Point 1, including the underground connections to the HL-LHC cavern, is now complete

A full-size, US-produced HL-LHC quadrupole magnet based on niobium–tin technology has passed a critical endurance test, another step towards confirming the technology’s viability inside accelerators
