“…Within the framework of the NET project, two tasks were launched at CEA Cadarache for the study of electrical joints [4], the upgrading of a test facility for subsize samples [5], and the fabrication and testing of subsize joints in the laboratory [6]. From the experience gained during this phase, an original design for the joints of the ITER coils was proposed by the European Union [7].…”

A new kind of superconductor, using the cable-in-conduit concept, is emerging, mainly in the context of fusion activity. At present no large Nb3Sn magnet in the world is operating using this concept. The difficulty of this technology, which has now been studied for 20 years, is that it requires major advances in several interconnected new fields, such as handling a large number (1000) of superconducting strands, high current conductors (50 kA), forced flow cryogenics, Nb3Sn technology, low loss conductors in pulsed operation, high current connections and high voltage insulation (10 kV), as well as demonstration of its economical and industrial feasibility. CEA has been very much involved, during the past ten years, in this development, which took place in the framework of the NET and ITER technological programmes. One major milestone was reached in 1998-1999 with the successful tests by Euratom-CEA of three full size conductor and connection samples in the SULTAN facility in Switzerland.

“…Measurements took place in the JOint Subsize Experimental FAcility (JOSEFA) located at CEA/Cadarache (France) [2]. This experimental facility enables us to characterize subsize joint samples at various injected current (up to 10 kA), temperature (range 5 to 20 K) and magnetic field (up to 3 T).…”

“…For the analysis, we used two models [5]: -the "quasi-static regime" where the He flow is stopped and the system slowly heated until quench. In that case the critical energy is: (2) where and are respectively the mass and the heat capacity of the element at constant pressure (helium, copper or stainless steel).…”

In the framework of the design and the development of the ITER PF coils, two subsize joint samples (scale 1/6) made of two different NbTi strands were manufactured at CEA/Cadarache (France) and were tested in the JOSEFA test facility at CEA. The characterization of joints was achieved in the areas of Resistance , Pulsed field losses, and Thermodynamic stability. The experimental results were interpreted with regard to the ITER specifications.
