Process Innovations for High Temperature Superconducting (HTS) Wire Manufacturing
Thermal and strain cycling tests for STI’s coated conductor have been performed with our newly updated critical current/tensile tester. The original goal was to carry out 1000 thermal cycles and 1000 strain cycles and measure Ic for pre and post cycling. The tape exceeded the goal. Thermal testing was successful with 2900 cycles and strain testing was carried out for 2000 cycles without any significant Ic degradation. Another important milestone was to produce lengths greater than 100m, a 2X improvement over reported performance reported in Q4/2019 report was completed.
