Method for manufacturing high-temperature superconducting conductors
First Claim
1. A method for manufacturing a high temperature superconducting conductor, said method comprising the steps of:
- a) providing an elongate substrate to a reactor, the elongate substrate having a major axis, the reactor having a longitudinal flow distributor, the longitudinal flow distributor having a top portion including an entrance, a bottom portion including a plurality of exits, and an internal distribution member provided between the top portion and the bottom portion, wherein the internal distribution member (i) includes a thickness, a width greater than the thickness, and a length greater than the width, and a plurality of through passages arranged non-uniformly along the length of the internal distribution member, and (ii) has no through passages aligned with the entrance;
b) shielding a first and second low temperature regions of the substrate with a first and second shield;
c) heating at least a portion of the substrate, located between the first and second low temperature regions, to a temperature sufficient to facilitate the formation of one of (i) a predecessor to a superconducting material and (ii) a superconducting material; and
d) flowing at least one precursor into the longitudinal flow distributor through the entrance, past the internal distribution member and out through the plurality of exits thereby longitudinally distributing a flow of the at least one precursor so as to communicate the at least one precursor with the heated at least a portion of the substrate so as to permit the formation of said one of (i) a predecessor to a superconducting material and (ii) a superconducting material, wherein the major axis of the elongate substrate is perpendicular to the flow as the flow exits the longitudinal flow distributor;
wherein the first and second shields substantially prevent flowing at least one precursor onto the first and second low temperature regions.

Abstract
A method for manufacturing a high-temperature superconducting conductor includes providing an elongate substrate to a reactor, the reactor having a longitudinal flow distributor. The longitudinal flow distributor has an entrance, a plurality of exits, and an interior distribution member provided between the entrance and the plurality of exits. The method further includes heating at least a portion of the substrate to a temperature sufficient to facilitate the formation of one of a superconducting material and a predecessor to a superconducting material. Further, the method includes flowing at least one precursor into the longitudinal flow distributor, through the entrance thereof, past an internal distribution member, and out through a plurality of exits, thereby longitudinally distributing the at least one precursor to form the superconducting material or predecessor thereof on the substrate.
