Cable-in-conduit conductors (CICCs) are applied in the superconducting magnets designed for fusion reactors, because of their high-engineering current transmission capacity and large heat removal capabilities. In previous research, CICCs exposed varying degrees of performance degradation during electro-magnetic (EM) loading cycles. To prevent this kind of degradation, CICCs must be designed...
A structural model has been developed for the VIPER cable, which is based on the Twisted Stacked-Tape Cable (TSTC) design and has four slots each containing 50 REBCO HTS tapes. Each slot contains a TSTC and the entire void space is filled with solder. The four slots are arranged around a central cooling channel. It is developed by Commonwealth Fusion Systems (CFS) in collaboration with the...
