Abstract :
Ferromagnetic polycrystalline dysprosium cores made from a rod-billet by hydropressing were used in concentrators to contribute up to 7.6 T in the gap between two conical end pieces. In each end piece the plane of easy magnetization is inclined at an angle to the central axis of the concentrator. Because of its magnetic characteristics a concentrator with textured dysprosium exceeds the known concentrators made from rare-earth materials. With this concentrator in a superconducting solenoid a total field of 21.2±0.2 T was obtained
