Abstract HTS tokamak SPARC is under development by the team lead by CFS, Cambridge, MA. The magnet will have toroidal coils operating at 20 T at a current in the 25 to 40 kA range. The ViewPoint describes VIPER, an advanced TSTC-based HTS cable that has a potential to meet all the criteria required for the HTS tokamak. If proven to be successful, the cable approach promises long lengths, hundreds of meters, of the high-performance cable with predictable and repeatable properties.

Qualitative Picture

The critical current of a model high-temperature superconductor (HTSC) with defects in the form of through holes (antidots) with a characteristic size greater than or of the order of the penetration depth of the magnetic field is calculated. To do this, the subprocesses equivalent to the trapping of the magnetic flux by the hole and the creation of a vortex at the edge of the hole are introduced into the model of layered HTSC. It is shown that accounting for these subprocesses leads to the appearance of a physical mechanism that allows us to correctly describe the non-monotonic dependence of the critical current on the characteristic size of the antidot, similar to that observed in the experiment. Calculations were performed for a pure superconductor and a superconductor containing nanoscale pinning centers. It is shown that the presence of nanoscale pinning centers along with antipoints does not change the qualitative picture of the influence of the antidot radius on the pinning character of the magnetic flux and the behavior of the critical current in the HTSC.

Controllable Reactor

The power equipments made of high-temperature superconductor (HTS) widely applied in power system in the recent years. A HTS adjustable reactor (HTS-AR) is a novel controllable reactor with the controllable windings made of HTS tapes. Shunt HTS-AR can regulate the reactive power of power and reduce the transmission loss. However, the leakage magnetic flux of the superconducting windings is relatively large, which may restrict the application of the HTS-AR in high-voltage transmission line. Basing on the research of the structure design for HTS winding, the characteristic analysis of magnetic and AC loss of HTS-AR with considering the structure of superconducting winding is shown in this study. The results show that the HTS winding with the ladder-like structure has a better performance compares with HTS winding with the solenoid structure.
