The many CERN-developed sensors and software programs of the FRAS (Full Remote Alignment System) have been successfully tested on a prototype magnet in preparation for the HL-LHC

The ATLAS and CMS collaborations have joined forces to establish the first evidence of the rare decay of the Higgs boson into a Z boson and a photon

The successful replacement of a coil in an HL-LHC niobium–tin quadrupole magnet by the US Accelerator Upgrade Project team has showcased this crucial technology’s flexibility and cost-effectiveness

Following the installation of kicker magnets that are more heat resistant and their successful tests during the SPS scrubbing run, the SPS is getting ready for High-Luminosity LHC operation.

A High-Luminosity LHC instrument known as the Beam Gas Curtain will be tested and start collecting data during Run 3

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
