Abstract
main stages of diffusion interaction between tin alloy with copper mat rix and the material of Nb filaments in superconductors with 1 central and 7 distributed tin sources, containing 2000 to 14000 filaments hav e been investigated. The main temperature conditions for intermediate and final heat treatment stages have been chosen. Tin distribution ove r a copper matrix cross section has been shown not to exceed 2 % at op timum heat treatment conditions. The conductor's current carrying capa city interconnection with heat treatment routes has been studied. It w as shown that the correct choice of a heat treatment route provides fo r high values of critical current density upto 1x10(5)A/cm2(12T)
