Abstract
The present invention relates to a method and an apparatus for producing superconducting devices and to superconducting devices. The method comprises determining one or more regions of reduced critical current density in the superconducting device and modifying the critical current density in the one or more regions of reduced critical current density, so as to increase the overall critical current or to decrease the overall AC losses of the superconducting device. The modifying comprises modifying the amount and/or distribution of the superconducting material in the one or more regions of reduced critical current density; and/or modifying the chemical composition of the superconducting material in the one or more regions of reduced critical current density; and/or decreasing the cooling temperature in the one or more regions of reduced critical current density. A superconducting device formed according to such method can also be provided.
