Crab cavities are critical to increase the number of interactions. After successful prototyping and testing, the US programme has entered series production.

Two 90-mm Niobium-titanium (NbTi) double-aperture quadrupole magnets, also called MQYY in the LHC vernacular, have been developed and manufactured by the companies Elytt Energy and SigmaPhi under the QUACO project for the High-Luminosity LHC upgrades.

Nb-Ti, MgB2 and ReBCO: a combination of conventional and novel superconductors for the powering of the HL-LHC magnets. Demo 2 and Demo 3 demonstration systems were successfully qualified at CERN in 2020.

CERN developed a digitizer to ensure the high-precision measurement of the current delivered to the superconducting magnets of the HL-LHC.

At LHC Point 4, a refrigerator that cools helium from room temperature to 4.5 K (-268.65 °C) has undergone major improvements in preparation for the HL-LHC

The cold diodes of the new triplet circuits will be installed in a dedicated cryostat in the LHC tunnel downstream of the triplet magnets and close to the LHC beam pipe.

26M£ funding will be major contribution to high luminosity LHC

Nearly one year after the start of the assembly activities the first 3-module-device Target Dump Injection Segmented (TDIS) unit is ready to be installed.

Novel cryostat units have been installed for the High-Luminosity LHC to allow insertion of room-temperature collimators in the LHC’s 1.9 K cryostats.
