Abstract
A round superconductor wire, method for fabricating same, and method for detecting quench in the same are disclosed. A round superconductor wire includes a superconductor wire former and at least one superconductor tape wound on the superconductor wire former. Each superconductor tape includes a substrate, a buffer film stack overlying the substrate, and a superconductor film overlying the buffer film stack.
