Status of the development program of a 60 kA HTSC current lead for the ITER toroidal field coils

In the frame of the European Fusion Technology Programme, FZK Karlsruhe and CRPP Villigen have started a development program for design and constructi on of a 60 kA current lead for the ITER Toroidal Field Coils using High Tem perature Superconductors. The task composes of four parts: material selecti on based on test results of 1 kA current leads, construction and test of a 10 kA and a 20 kA lead using the selected HTSC material giving proof of the modularity and scale-ability of the design, and finally construction and t est of a 60 kA current lead which will replace an existing conventional lea d in the TOSKA facility at FZK. As result of part one, Bi-2223 tapes electr ically stabilized by AgAu material were selected for the further developmen t program. Two 10 kA HTSC modules using different conductor designs have be en manufactured in industry and are being fabricated in the institute. The paper describes the status of the development program. Experimental results of the first step and first results of the 10 kA HTSC lead are given.
