Abstract
A method of forming a superconducting conductor is disclosed. The method provides translating a substrate tape through a deposition chamber and along a helical path, where the helical path has multiple windings of the substrate tape and each winding of the substrate tape extends along a feed path and a return path. The method further provides depositing a HTS layer overlying the substrate tape within a deposition chamber, wherein the deposition chamber houses the substrate tape along the feed path but not the return path.

A method of forming a superconducting conductor comprising:
- translating a substrate tape through a deposition chamber and along a helical path, the helical path having multiple windings of the substrate tape, each winding extending along a feed path and a return path, the deposition chamber including a first lateral wall and a second lateral wall defining therebetween a deposition zone;
- and
- depositing a HTS layer overlying the substrate tape within the deposition zone of the deposition chamber, the substrate tape exiting the deposition chamber through the second lateral wall such that the deposition chamber houses the substrate tape along the feed path but not the return path.
A method of forming a superconducting conductor comprising:
- translating a substrate tape having a dimension ratio greater than about 100 through a deposition chamber and along a helical path comprising a feed path and a return path, the substrate tape comprising multiple windings comprising a first winding, a last winding and interior windings, the deposition chamber including a first lateral wall and a second lateral wall defining therebetween a deposition zone;
- translating the substrate tape along the feed path having a feed translation direction Dr and along the return path having a return translation direction Dr wherein at least the interior windings extend along the feed path in a rectilinear manner between a feed guide and a take up guide;
- directing the substrate tape along the return path to shift a distance Ds in a direction perpendicular to Df′, and depositing a HTS layer overlying the substrate tape within the deposition zone of the deposition chamber, the substrate tape exiting the deposition chamber through the second lateral wall such that the deposition chamber houses the substrate tape along the feed path but not the return path.
A method of forming a superconducting conductor comprising:
- feeding a substrate tape having a dimension ratio not greater than about 100 into a deposition chamber from a feed reel and taking up the substrate tape exiting from the deposition chamber with a take-up reel wherein the feed reel and take-up reel are external to the deposition chamber, the substrate tape including a substrate and a biaxially textured buffer layer overlying the substrate, the deposition chamber including a first lateral wall and a second lateral wall defining therebetween a deposition zone;
- translating the substrate tape along a helical path comprising a feed path and a return path, the substrate tape comprising multiple windings having a first winding, a last winding and interior windings, wherein the substrate tape translates along the feed path having a feed translation direction Df and along the return path having a return translation direction Dr, at least the interior windings extending along the feed path in a rectilinear manner between a feed guide and a take up guide;
- directing the substrate tape along the return path to shift a distance Ds in a direction perpendicular to the feed translation direction Df, the return translation direction Dr extending along an angle not greater than about 10.0° relative to the feed translation direction Df′;
- and
- depositing a HTS layer to overlie the biaxially textured buffer layer within the deposition zone of the deposition chamber, the substrate tape exiting the deposition chamber through the second lateral wall such that the deposition chamber houses the substrate tape along the feed path but not the return path.
