Present Status and Recent Developments of the Twisted Stacked Tape Cable Conductor
The high magnetic field performance of a 40 tape twisted stacked tape cable (TSTC) conductor made of 4 mm width 0.1 mm thick REBCO tapes was successfully tested. The critical current was 6.0 kA, with the n value of 35, at 4.2 K with a background field of 17 T. No cyclic load effect was observed between 10 and 17 T with the maximum Lorentz load of 102 kN/m. Various issues, such as sample length, nonuniformity of termination resistances, and soldered joint of a coated tape cable, with regard to a TSTC conductor are discussed. Large scale conductor designs of various scalable TSTC conductors are discussed, taking into account current densities and stabilizers.
