Abstract
Viability of BSCCO-2212 round wires for high field magnet applications is being investigated within the Very High Field Superconducting Magnet Collaboration (VHFSMC). Three BSCCO-2212 wires of different designs were homogeneously flat-rolled to decreasing sizes to study the effect of deformation as a function of the precursor used and of the architecture parameters of the wires. After heat treatment at Oxford Superconducting Technology (OST), size variations of round and deformed samples were measured, and their transport properties characterized at 4.2 K and at magnetic fields up to 14 T. The wire made with granulate precursor was the most homogenous. The wires made with powder precursor showed instead non-monotonic behavior in Ic and even more so in the n-value.Keywords
