Conduction-cooled 60 A resistive current leads for LHC dipole correctors

The powering of the LHC close orbit dipole corrector magnets will be made via 752 electrical circuits rated for a maximum current of 60 A. A total number of 1504 current leads will transport the current, through the cryostat main vacuum insulation, from room temperature to the 1.9 K superfluid liquid helium bath. This report summarizes the lead's optimisation principle, including the cooling method and the choice of material, as well as the integration issues and the results of the measurements performed on prototype leads manufactured and assembled at CERN.
