The invention relates to a method for producing a superconductive element to be used as a wire-in-channel superconductor in magnetic resonance imaging (MRI) and in nuclear magnetic resonance (NMR) applications, which superconductive element contains a superconductive wire and a copper component having a longitudinal groove and the superconductive wire being positioned in the groove. In order to produce the wire-in-channel superconductive element by a mechanical contact between the superconductive wire and a wall of the groove in the copper component, at least one contact surface is coated with a lead free solder material before having the mechanical contact. In order to enhance the thermal and electrical conduction and to create a bond between the said components the soldering material is fused in annealing process step.

Method for producing a superconductive element

The invention relates to an assembly () of metal elements constituting a precursor for a superconductor. The assembly comprises at least one conductor element () adapted to provide a superconducting filament in the finished superconductor, and at least one doping element () providing a doping source for doping the conductor element. The invention also relates to a method suitable for producing a superconductor.
