Internal
tin Nb3Sn composites, used in high energy physics research, have a
performance advantage over bronze style wires; however, the strength of the
various composite elements varies greatly.
This leads to processing difficulties, especially for very high tin
(i.e., high Jc) composites. Additionally,
it is advantageous for the Nb3Sn compound to incorporate Ti; however,
this can be costly and sometimes hard to obtain.
This project addresses both of these difficulties by incorporating the Ti
in the tin core rods. This
strengthens the tin component while simultaneously lowering the strength of the
Nb component, thus evening-out the strengths of the composite elements.
Phase I will establish a baseline process and then scale up to prototype
Sn-Ti core rods. These core rods will be evaluated in internal tin composites.
Ultimately, a process will be established to supply high quality Sn-Ti
core rods for use in internal tin Nb3Sn composites.
Commercial Applications And Other Benefits as described by awardee: The tin-titanium core rods developed here should be applicable for use in internal tin wires used in commercial high field magnets such as are used in NMR (chemistry and pharmaceuticals) as well as in synchrotron machines (x-ray lithography) used in thin film fabrication (electronics).
