[en] A preliminary assessment was made of the feasibility of scaling up the laboratory techniques of making filamentary Nb₃Sn superconductors using powder metallurgy to commercial fabrication process. The purpose of the effort is divided into two tasks. The first one is to demonstrate that sintered niobium rods infiltrated with tin can be reduced in area of approximately 10⁴. The second task pertains to the extrusion by conventional manner a copper billet containing several sintered rods each encapsulated in tantalum. The ultimate goal of the project is to establish optimal processing parameters that are suitable for the production of long lengths of fully stabilized, large current and high field conductors
