The magnet, named MQXFB03, is 7.2 metres in length. It is the first of ten that will be needed for the HL-LHC. (Image: CERN) The Large Hadron Collider (LHC) needs specific types of magnets to tightly control the beams of particles at its collision points. Called final-focusing quadrupoles, these magnets are installed in the LHC’s interaction regions around the experiments. For the high-luminosity upgrade of the LHC (HL-LHC), the final-focusing magnets at ATLAS and CMS will need replacing. Tests at CERN have now confirmed that the quadrupole magnets newly designed to replace them will work. Unlike the LHC magnets, which are made from niobium–titanium (Nb–Ti), the new magnets are made from a more challenging material: niobium–tin (Nb3Sn). “Given the brittleness of Nb3Sn and the fact that its coils are very rigid, assembling Nb3Sn magnets requires close attention,” explains José Miguel Jiménez, head of the Technology department. “This makes it a much bigger challenge than ....
