We report the combination of two separately developed materials processing technologies which together have made possible the production of single phase fibers of (Hg,Re)-Ba-Ca-Cu-O ((Hg,Re)-1223). These fibers have shown T c values of 132 K, irreversibility fields of 2.3 T at 77 K and I c values as high as 10 A and 40 A at 77 and 4.2 K, respectively. One salient use of these fibers is their application to the HTS section of a resistive/superconducting hybrid current lead. Such an application offers greater system cooling efficiencies and the ability to operate in higher magnetic fields then current leads based upon the more commonly used Y-Ba-Cu-O (123) and Bi-Sr-Ca-Cu-O (2223) compounds.
