Multifilamentary Nb[sub 3]Sn superconductors manufactured by the internal tin method are lately considered in view of their possible application in windings of very large magnetic systems such as for example ITER. Main stages of diffusion interaction between tin alloy with copper matrix and the material of Nb filaments in super-conductors with 1 central and 7 distributed tin sources, containing 2,000 to 14,000 filaments have been investigated. The main temperature conditions for intermediate and final heat treatment stages have been chosen. Tin distribution over a copper matrix cross section has been shown not to exceed 2% at optimum heat treatment conditions. The conductor's current carrying capacity interconnection with heat treatment routes has been studied. It was shown that the correct choice of a heat treatment route provides for high values of critical current density up to 1 [times] 10[sup 5] A/cm[sup 2] (12T).
