“…The achieved minimum fracture toughness of CW+AG type A conduit is 136 MPa•m 1/2 , a little higher than the required minimum value of 130 MPa•m 1/2 . The achieved toughness in CW+AG condition is lower than the one obtained by Ozeki et al [18], but it is close to the results reported by P. R. walsh [15].…”

High manganese steel is a promising choice as a jacket material for Nb 3 Sn superconducting magnet due to the low thermal expansion, high strength combined with good ductility. One kind of high manganese steel with the Mn content of about 21% was developed for reviewing the mechanical properties at 4.2 K. In this paper, the mechanical performances of the developed high Mn steel in solution annealed as well as in cold worked and aged condition were tested. Influences from cold working and aging processes on microstructure and mechanical properties were analyzed.

“…This special grade of austenitic steel with high manganese content is in fact presently used for the ITER CS CICC production [92]. Another possibility in the same line is that of using Ti jacket: CICC short samples employing Ti [160] have demonstrated improved performances with respect to standard steel [161], and a full conductor length was manufactured [162] and wound, to constitute the ITER toroidal field conductor insert [162], operated in the CSMC facility in Japan [157]. In this case, the higher cost of Ti with respect to stainless steel, and some additional development required in the technology of the welding should be balanced against the expected performance improvement.…”

We review progress in the design of high field superconducting cable-in-conduit conductors (CICCs) for fusion applications, with special attention to the results of recent key experiments, leading to the state-of-the-art CICC technology: the ITER Toroidal Field and Central Solenoid programs, the EFDA Dipole conductor development program, the NHFML Hybrid Magnet project, the EU-TF Alt conductor demonstration, and the CRPP React & Wind flat cable test. For these projects, the main CICC design driver was the mitigation of Nb 3 Sn conductor performance degradation with electro-magnetic loading cycles. This was achieved by proper choice of cable layout and of conductor geometry, depending on the specific operating conditions and project requirements. In all cases, the necessity to limit cable movements inside the conductor jacket was identified to be of crucial importance. The main aspects of CICC manufacture are also discussed here, at least for what is the experience gained by the authors in both CICC jacketing and cabling processes. Finally, the state of the art of high-temperature superconducting (HTS) cables is discussed: at present, this technology is still in its infancy, but it is highly likely that major technological improvements could eventually lead to a widespread use of HTS CICCs.
