“…Besides the ITER CS CICC cable, calculations of ∥ Φ max ⁄ have been performed for cable in other Nb 3 Sn CICC including the ITER TF conductor and other CICCs tested and reported in the recent past [39][40][41][42]. The cable characteristics and calculations for each cable design are given in descending order of ∥ Φ max ⁄ in Tables I and III. 3.5.…”

The Cable-In-Conduit-Conductor (CICC) for the ITER tokamak Central Solenoid (CS) has undergone design change since the first prototype conductor sample was tested in 2010. After tests showed that the performance of initial conductor samples degraded rapidly without stabilization, an alternate design with shorter sub-cable twist pitches was tested and discovered to satisfy performance requirements, namely that the minimum current sharing temperature (T cs ) remained above a given limit under DC bias. With consistent successful performance of ITER CS conductor CICC samples using the alternate design, an attempt is made here to revisit the internal electromagnetic properties of the CICC cable design to identify any correlation with conductor performance. Results of this study suggest that there may be a simple link between the Nb 3 Sn CICC internal self-field and its T cs performance. The study also suggests that an optimization process should exist that can further improve the performance of Nb 3 Sn based CICC.

“…However, "TFPRO2 OST2" is also characterized by a comparatively very small void fraction of 27.7%, only higher than "MF HFML STP" and "MF HFML LTP" [40]. The small void fraction may have prevented increases in T cs , while the cabling that resulted in ∥ Φ max ⁄ ≈ 0.11 may have prevented degradation.…”

“…In addition, TFPRO samples make use of crimping rings at both leg ends to avoid any strain relaxation during the joint fabrication, and the central spiral was plugged during tests. More detailed information on TFAS and TFPRO samples can be found in [2] and [4], respectively. Once in the facility, a length of about 450 mm on each conductor is submitted to the SULTAN transverse background field.…”

“…Once in the facility, a length of about 450 mm on each conductor is submitted to the SULTAN transverse background field. The voltage drop over 450 mm (V 450 ) is measured by voltage taps welded onto the jacket, and the temperature is measured upstream and downstream by sensors glued onto the jacket [2,4]. The current sharing temperature T cs is defined at a voltage drop of 4.5 µV, considered equivalent to an average electric field of 10 µV/m.…”
