<p>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 current applied, d) continuously moving at least one part of the band in the longitudinal direction of the band through the contact section and/or through the measurement section to electrically contact the moving band so as to generate a transport current progressing through the band in the longitudinal direction of the band, e) detecting a physical measured variable on the basis of the generated transport current in relation to the measurement section by means of the measurement contacts during the movement of at least one part of the band through the measurement section, wherein the physical measured variable is a measure of the superconducting electrical transport properties of the band section or a part of the band.</p> |
