Abstract :
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 TCS, pulsed field losses, and thermodynamic stability. The experimental results were interpreted with regard to the ITER specifications.
