High-Luminosity LHC (HL-LHC)

The High-Luminosity Large Hadron Collider (HL-LHC) project aims to crank up the performance of the LHC in order to increase the potential for discoveries after 2028. The objective is to increase luminosity by a factor of 10 beyond the LHC’s design value. The project is led by CERN with the support of an international collaboration of 44 institutions in 20 countries.
 
Luminosity is an important indicator of the performance of an accelerator: it is proportional to the number of collisions that occur in a given amount of time. The higher the luminosity, the more data the experiments can gather to allow them to observe rare processes.

QUACO at the finish line

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.
