Manufacture and test of ITER 10 kA HTSCL prototypes

10 kA High Temperature Superconducting Current Leads (HTSCL) are designed to carry current for the ITER Correction Coils (CC). Current leads provide the transition from 4.5 K low temperature to room temperature. Before the supply of the HTS current lead series, a pair of prototypes was manufactured and tested in 2014 based on the quality control and test requirements from the ITER Organization (IO). This paper summarizes the major design features of the prototypes, followed by a discussion of the manufacturing and testing.
