Superconducting wires for NMR-application
- Bochvar All-Russia Scientific Research Inst. of Inorganic Materials, Moscow (Russian Federation); and others
NMR analytical systems and MRI imaging magnets are now the very important area of NbTi based superconductors application. The characteristic features of these magnet systems are stability and high homogeneity of magnet fields. That is why the requirements for superconductors for that application include long unit length, low packing factor (P.F.) of superconducting alloy, high conductivity of matrix, precise dimensions of the filaments and the wire as a whole. Here, the results are presented on production of NbTi based conductors in copper matrix with wire diameters from 0.8 to 1.75 mm, filament numbers 12--42, filament diameters 55--130 {micro}m and packing factors 6.5--23%, with application in various NMR and MRI magnet systems. It is shown, that wire length could be tens of kilometers. Critical current, RRR and dielectric strength in all cases exceed requirements.
