Characterization of Filament Damage on Externally and Internally Etched Bi[2]Sr[2]CaCu[2]O[8-x] (Bi-2212) Superconducting Wires after Tensile Strain

Abstract

Bi2Sr2Ca1Cu2O8-x (Bi-2212): a superconducting material that is able to produce magnetic fields greater than 25 T. The study of sub-atomic particles in physics is progressing and needs higher magnetic fields for large particle accelerators. Bi-2212 is currently the only superconducting round wire capable of producing magnetic fields in excess of 20 T. Bi-2212 filaments in the silver matrix are brittle and vulnerable to damage during mechanical testing. This research seeks to understand how the damage varies for different chemical etches and how that damage is influenced by various levels of strain.
