HTS current leads for the LHC.

Author(s) : BALLARINO A.

Summary

The Large Hadron Collider requires the transfer of more than 3 million amperes of current form the power converters, working at room temperature, into the liquid helium environment, where the magnets are operating. To reduce the heat load into the liquid helium, CERN aims to use high temperature superconducting (HTS) material for current leads having ratings between 600 and 13 000 A. A prototype for these current leads incorporating HTS sections have recently been tested. After a brief reminder of the motives of the choice of the lead design and cooling method, the status of the project and the cost-benefit consequence of its application are reported.
