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)
