powder as the tin source. A novel octagonal PIT design that incorporates dispersion strengthened copper as well as a hexagonal PIT design were fabricated. In this paper, we compare the critical current and strain properties of the octagonal PIT conductor designs with standard hexagonal PIT conductor designs.
