“…First, the cable dc performance is compared with the strand data from the strand manufacturer [4]. An effective self-field factor k eff [5] is defined in such a way that I cable c (B eff ) ∼ = NI strand c (B eff ), where B eff = B b + k eff I c (B b background field, N number of strands).…”

“…These are used for the manufacture of superconducting cable employed as currentcarrying elements in the magnetic system for International Thermonuclear Experimental Reactor. The cable houses several thousand strands of superconducting wire in a copper matrix, each strand being 2…5 mμ in diameter [2]. Such cables must be capable of meeting a number of stringent requirements, i.e.…”

Using atomic force, optical and electron microscopy methods, the changes in the microstructure and phase composition were investigated for the alloy Nb47%Ti used for the manufacture of superconducting cable employed as current-carrying elements in the magnetic system for International Thermonuclear Experimental Reactor. The test samples were prepared from the superconducting wire at an intermediate step of the drawing process for the area reduction Ø1.3→Ø1.2 mm. The effect of cold drawing and intermediate annealing on the properties of as-worked Nb-Ti alloy was assessed. Local strain zones were found to occur in the rupture area. The shape and chemical composition of Nb-Ti wire was examined for both a defect-free area and the rupture area. A Nb diffusion barrier was found to occur in the copper matrix of NbTi wire.

“…As an example a comparison between CEA results on strand #3 and Bochvar measurements on a similar strand (here called strand #4) [8] showed some differences illustrated in Table III. Fit #3 is defined in PFIS operating range with same exponents as fit#1. Fit #4 is similar but with free exponents.…”

In the framework of the R&D for the ITER Poloidal Field Coils (PFC), a testing campaign was achieved on NbTi strands used in PFC-relevant modules. Three candidate NbTi strands have been used for manufacture of two Full-Size Joint Samples (PFIS and PF-FSJS) and the PF Conductor Insert (PFCI): -one strand manufactured by Europa Metalli (Italy), Ni plated and 0.81 mm diameter -one strand manufactured by Alstom (France), with a CuNi barrier and 0.81 mm diameter -one strand manufactured by Bochvar VNIINM (Russia), Ni plated and 0.73 mm diameter An extensive test campaign has been performed at GHMFL (CNRS, Grenoble) in 2003 using the CEA VTC facility at temperatures ranging from 4.2 K to 7.5 K and at magnetic fields ranging from 2.5 to 10.5 T.The results showed that all three strands have quite close performances in the ITER PFC operating range despite their structural differences and that due to the critical current density curvature with temperature, they fail to meet the 1.5 K PFC temperature margin criterion by 0.2 to 0.3 K. Additionally, applications of corresponding fits to PF-FSJS tests showed consistent results and finally a brief discussion on fitting formula is presented.
