Project summary

The objective of this Project is the creation of new type super-conducting NbTi wires applicable to 7-10 T magnetic fields and wires applicable to 1-5 T magnetic fields with higher technical and economic characteristics. The wires may be applied to magnetic accelerators including LHC, NMR-tomographs and other magnetic systems. Within this Project it is proposed: to develop a new alloy (Nb-Ti-Ta) for the conductors applicable to high magnetic fields, technologies of melting, casting and processing of Nb-Ti-Ta ingots in order to produce high-pure and high-homogeneous billets having a structure suitable for further processing; to develop new designs and technology of composite billet assembling; to optimize the operating conditions of thermomechanical treatment of newly designed wires; to develop the artificial pinning center superconductors for magnetic systems of different applications.

ASRIIM pioneered in applying the method of creating of superconductors with artificial pinning centers (APC). These works demonstrated a high validity of APC-method for the production of commercial superconductors. The technology of APC superconductor's production is free of the necessity of fabrication of costly high-homogeneous ingots from Nb-Ti alloy and there is no need to carry out the prolonged intermediate heat treatments. All these advantages may provide a significant drop in the production cost, up to 40%.

The developed technology allows to produce wires of a wide-purpose and to realize a wide range of conductor designs.

The research is supposed to be done along the following basic lines:

- development of physical and material study principles of the production of superconductors having high superconducting characteristics;
- development of design and manufacturing technology for new high-purity starting materials to be used for superconductors. In a time of the Project's realization we intend to develop the laboratory technologies and to manufacture superconductor's prototypes.

The anticipated characteristics of the conductors are tabulated in Table:

Some foreign firms, which have a great experience in the production, testing and application of superconducting materials, are proposed to be the collaborators of the Project.

Potential role of foreign collaborators in this Project consists in joint developing of superconducting wire's designs, mutual consulting on the Project realization, measuring of electro-physical characteristics of the prepared samples, joint planning, discussing and publishing the experimental results.
