Abstract

The description of design of advanced technological setup for the synthesis of composite long-length superconducting tape on the basis of Nb3Sn is presented. The design of setup has allowed us to produce the Nb3Sn tape with the record magnitudes of density of critical current Jc in the magnetic fields H of above 10 T (H > 10 T). The high current density conductivity property is reached as a result of both the optimization of technological process of the Nb3Sn tape synthesis and the increase of thickness of superconductor layer, which is characterized by the homogeneous physical properties.
