Abstract: A method and device for quality control of superconducting bands includes: cooling a section of the superconducting band to a temperature at which said band section becomes superconducting, generating an electrical transport current in the superconducting band section in the longitudinal direction of the band by contacting with a contact assembly, contacting the cooled band section with electrical contacts of the contact assembly, which are spaced apart in the longitudinal direction of the band, in order to form a measurement section over a partial length of the band section, continuously moving at least one part of the band through the contact section and/or measurement section to generate the transport current, detecting a physical measured variable using measurement contacts, wherein the physical measured variable is a measure of the superconducting electrical transport properties of the band section or a part of the band.

Abstract: The invention relates to a method and a device for the quality control of superconducting bands with regard to the critical current carrying capacity of the band, wherein the method comprises the following steps: a) cooling a section of the superconducting band to a temperature at which said band section becomes superconducting, wherein the length of the band equals a multiple of the band section length, b) generating an electrical transport current in the superconducting band section in the longitudinal direction of the band by contacting with a contact assembly, which comprises electrical feed and dissipation contacts spaced apart in the longitudinal direction of the band in order to generate the transport current between them, c) contacting the cooled band section with the electrical contacts of the contact assembly, which are spaced apart from one another in the longitudinal direction of the band, in order to form a measurement section over a partial length of the band section to which the transport curre

Abstract: A band-shaped high-temperature superconductor (HTSL) with high critical current density can be produced economically in a wet-chemical process. In the process, a first precursor solution is applied to a carrier, dried, and annealed. Additional precursor solutions may then be applied, with the first precursor solution contain little or no pinning centers, and any subsequent precursor solutions contains a higher concentration of pinning centers than the first precursor solutions.

Abstract: A wet-chemical method for producing strip-shaped high-temperature superconductors with a substrate, optionally with a buffer layer and with a high-temperature superconductive layer is improved by increasing the texturing and the layer thickness of the high-temperature superconductive layer. To this end, precursor solutions are applied in layers to the substrate, of which the first is low in fluorine or does not contain fluorine, and the following have a fluorine concentration that increases with each layer.

Abstract: The invention relates to a method for coating shaped bodies made of a superconducting material based on (Y/SE)BaCuO. The invention is characterized in that a coating consisting of a coating material is applied to at least one part of a surface of the shaped body, whereby the coating material at least partially melts at a lower temperature than that of the material of the shaped body and/or is flowable at a lower temperature than that of said material. The shaped body with the applied coating material is heated to a temperature at which the material of the shaped body does not yet melt and/or is not yet flowable, however at which the coating material is at least partially melted thereon and/or is in a flowable state.
