Abstract :
We have constructed a prototype 1-m long, coaxial ac superconducting power transmission cable utilizing Nb3 Ge-clad tapes, Tapes up to 20-m long were produced by pulling 25-μm thick by 0.64-cm wide copper substrates through a continuous coating chemical vapor deposition reactor. Nb3 Ge layer thicknesses in the range 3-5 μm were deposited on both surfaces and around the edges of the substrate. A total of 50 m of Nb3 Ge-coated tapes was incorporated in this cable, with all tapes exhibiting critical current densities Jc @ 14 K 
A/cm2. The cable was fabricated after the BNL double-helix design. Losses measured in the cable were found to be high, ∼ 1 mW/cm2at 500 rms A/cm, and comparable to losses in similar 1-m Nb3 Sn-based cables. We believe that these high losses are not a result of material dependent properties.
