Title & Task

WG 7

Critical current measurement method of Nb3Sn composite superconductors

 

To develop a method for the critical current measurement on
Nb3Sn composite superconductors produced by the bronze process
or the internal Sn diffusion process with or without ternary
addition. Round wire, lc<1000A, B<0,7Bc2, Cu vol%: 10-70%,
n>10, T=4,2K. The Nb3Sn wire is used in much higher magnetic
fields, and much more sensitive to mechanical strain than the
NbTi wire. (See New Work Item Proposal 90(Secretariat)15 and
its results of voting 90(Secretariat)20).
