Abstract :
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 μm and packing factors 6.5-23%, applicated in various NMR and MRI magnet systems. It is shown, that wire length could be tens kilometres. Critical current, RRR and dielectric strength in all cases exceed requirements
