Schematic layout of a Cold Powering System (left). Nb-Ti cables are in a saturated liquid helium bath at 4.5 K, MgB2 cables operate between 4.5 K and about 20 K, and REBCO cables operate between 20 K and about 60 K. Layout of the |117| kA MgB2 cable assembly of the Superconducting Link for the HL-LHC Triplets (right). There are in total nineteen cables: two 18 kA cables for the Nb3Sn quadrupole magnets, two 15 kA cables for the Nb-Ti Separation Dipole magnet (rated at 18 kA), three 2 kA cables for the Trim circuit (rated at up to 7 kA), and six coaxial 2 kA cables, i.e. twelve 2 kA polarities. The maximum field experienced by the superconductor is 1 T. The total external diameter is about 90 mm. The weight is about 23 kg/m.
