MONOFILAMENT FOR PRODUCING AN NB3SN-CONTAINING SUPERCONDUCTOR WIRE, ESPECIALLY FOR INTERNAL OXIDATION
First Claim
1. A monofilament for producing an Nb3Sn-containing superconductor wire, comprising:
- a powder core comprising an Sn-containing powder,a reaction tube composed of an Nb alloy comprising Nb and at least one further alloy component X,wherein the powder core is disposed radially within the reaction tubeat least one source for at least one partner component Pk,wherein each source is disposed in a unitary radial position in the monofilament and comprises at least one source structure;
wherein the alloy component X and the partner component Pk are selected to form precipitates XPk through reaction annealing of the monofilament, in which Sn from the powder core and Nb from the reaction tube react to produce Nb3Sn, anda moderation tube disposed within the reaction tube and in which the powder core is disposed.

Abstract
A monofilament (100) for producing an Nb3Sn-containing superconductor wire (33) includes a powder core (1) with an Sn-containing powder, a reaction tube (3) composed of an Nb alloy that includes Nb and at least one further alloy component X. The powder core is disposed within the reaction tube. The monofilament also includes at least one source (4) for at least one partner component Pk. A respective source includes one or more source structures at a unitary radial position in the monofilament. The alloy component X and the partner component Pk form precipitates XPk on reaction annealing of the monofilament in which Sn from the powder core and Nb from the reaction tube react to produce Nb3Sn. The powder core is disposed in a moderation tube, which in turn is disposed within the reaction tube. This provides a monofilament for a powder-in-tube based Nb3Sn-containing superconductor wire with improved current carrying capacity.
