Coupled mechanical–electromagnetic–thermal–hydraulic effects in Nb3Sn cable-in-conduit conductors for ITER

“…This is due to the outward movement of the cable within the jacket combined with the relatively low longitudinal stiffness of the cable compared to the supporting structures (mostly the jacket). The pressure at the curved ends reaches a maximum and the corresponding gap between the cable and the jacket on the inner surface is in reasonable agreement with previous analysis of ITER coil test results (Hamada et al 2002). The compression onto the outer jacket surface produces a transverse compression of the cable and allows an outward movement of the inner high-field surface.…”

“…However, the problem of how representative the conductor sample is for simulating conductor-in-coil conditions is still under discussion. It is addressed here by considering the particular case of the path going from the LMI strand (Lee et al 2000) to the Toroidal Field Model Coil (TFMC), tested in 2001and 2002at FZK Karlsruhe, Germany (Ulbricht et al 2005, through its associated Full Size Joint Sample, the TFMC-FSJS, tested in 1999 at SULTAN (Ciazynski et al 2000). Even so, one will still need some extrapolation in going from the Model Coil to the real ITER coil, including the fact that the two will not necessarily use the same conductor.…”

Relation Between Contact Resistance and Twist Pitches in Superconducting Doublets

“…3 and 4 respectively. A maximum value of the applied force to the doublet in the experiment was approximately 100 newtons (667 N/m) because the compressive force between the strands due to electromagnetic force during an excitation of CICC's magnets is assumed to be less than 600 N/m [8]. In each figures, the horizontal axis is for the force applied to the doublet.…”
