Project summaryThe 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:
Critical current density: at 2 K
1190 A/mm2 11 T
2285 A/mm2 9 T
At 4,2 K
1190 A/mm2 8 T
2275 A/mm2 6 T
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.
