Abstract:
1. A method of continuously coaling at least one substrate with a buffer layer as a support for a ceramic superconducting material comprising: loading the at least one substrate having a width and opposite major surfaces onto a respective feed spool; feeding the at least one substrate across a substrate block within a deposition zone in a vacuum deposition chamber wherein a coating generated from a single deposition source is applied to the at least one substrate white the at least one substrate is bombarded by ions from a dual RF-ion source along the deposition zone; forming at least one coated substrate within the deposition zone; and reloading the at least one coated substrate onto a respective take-up spool, wherein the dual RF-ion source includes first and second RF-ion sources bi-laterally oriented with respect to the at least one substrate, on the same side of the substrate, and located such that a projection on a major surface of the at least one substrate of a line intersecting the first and second RF-ion sources is substantially perpendicular to the longitudinal axis of the at least one substrate so as to be aimed at respective first and second portions of the same major surface of the at least one substrate and bombard the respective first and second portions of the same major surface of the at least one substrate, wherein the first portion and the second portion each span one-half the width of the at least one substrate such that the first and second portions span an entirety of the width of the at least one substrate and wherein a separator is disposed within the deposition chamber, between the bilaterally oriented dual RF-ion sources, and in closer proximity to the substrate block than to the dual RF-ion sources, the separator being oriented along a direction that longitudinally bisects the substrate block and functioning to barricade impingement of ions from the first RE-ion source on the second portion and barricade impingement of ions from the second RF-ion source on the first portion.
