A combined superconducting magnetic system with a homoge-neous field of up to 20 T was developed. The system consists of the several solenoidal sections and a magnetic flux concentrator from hydroextruded dysprosium. Sections are wound from NbTi, Nb3Sn wires and Nb3Sn tape. To increase the uniformity of the magnetic field, a magnetic shield made of Nb3Sn tape was made. The magnetic field achieved in the gap between the ends of the concentrator has a high spatial uniformity ΔН/Н ~ 5⋅10–5.

Key words: strong and uniform magnetic fields, combined magnetic device, magnetic flux concentrator, hydroextruded dysprosium.
