Abstract:
1. A method for forming a superconducting wire with a tape substrate, the method comprising: dispensing the tape substrate from a first reel; introducing the tape substrate into at least one reaction chamber comprising at least one distribution head and at least one light source; dispensing a laminar flow of reactant materials mixed with a carrier gas from the at least one distribution head to a deposition region between the at least one distribution head and the substrate surface to continuously form at least one layer of buffer material on the tape substrate; introducing the tape substrate into at least one transition chamber comprising at least one heating element to adjust the temperature of the tape substrate; introducing the tape substrate into at least one other reaction chamber comprising at least one distribution head and at least one light source; dispensing a laminar flow of reactant materials mixed with a carrier gas from the at least one distribution head to a deposition region between the at least one distribution head and the substrate surface to continuously form a layer of the superconductor material on the layer of buffer material; and spooling the tape substrate comprising the layers of buffer material and superconductor material onto a second reel, wherein UV light, visible light, or a combination of UV and visible light is directed from the light source to the surface of said substrate with a reflector during the formation of at least one of the layers of buffer material and superconductor material; and wherein the tape substrate is exposed to normal atmosphere during at least one of the dispensing step and the spooling step.
