The reference design for the Large Hadron Collider (LHC) at the European laboratory for particle physics, CERN is based on the generalised use of High-Temperature Superconductor (HTS) current leads.This paper discusses the envisaged cooling methods for these HTS leads and lists the possible gains and drawbacks for the cryogenic system linked to these different solutions.The aspects considered for this comparison are the design of interfaces, the adaptability to load changes, the design of the heat exchangers for the lead cooling and the exergetic costs of refrigeration within the already well defined cryogenic infrastructure for the LHC machine.
