The HL-LHC Cold Powering Systems transfer the current from the power converters, located in the new underground galleries, to the new superconducting magnets of the HL-LHC Inner Triplets and Matching Sections at P1 and P5

An important milestone was achieved in June 2020 with the successful test at CERN of a demonstrator of the cold powering system for the HL-LHC magnets. Demo 2 incorporates a superconducting 60-m long power transmission line, the Superconducting Link.
