The first series HL-LHC 120 kA MgB₂ cable assembly, produced in industry, was delivered to CERN in January 2020.
It contains the MgB₂ cables, nineteen in total, that will feed with current the HL-LHC triplets. It is about 140 m long, it has a diameter of about 90 mm, and it will transfer a DC current of about 120 kA at up to 25 K. It will be integrated at CERN into a long flexible cryostat to form an electrical transfer line called "Superconducting Link".
