While the conception, the optimization and the detailed design of the LHC leads was made at CERN, where prototypes of each type of current lead were built and tested, the series production of the components is being carried out in companies and external laboratories on the basis of the CERN
specifications and drawings. The electrical characterization
at cryogenic temperatures of the series of HTS leads is also made by external laboratories.
