## Title

    reaction

## Description

- description: Enhancing the characteristics of Nb3Sn superconducting wire is essential
    for the development of magnets for fusion reactors like ITER and DEMO. It has
    been established that Ti-doping has a significant effect on enhancing the upper
    critical magnetic field (Bc2). Ti is generally doped into Nb or Sn-alloys in practical
    Nb3Sn superconducting wires, and it would be preferable to add Ti to the Sn side
    from a manufacturing perspective. However, Ti-doping on Sn sites could form some
    undesirable stable compounds layers at the interface with Nb as a diffusion barrier
    for Sn during the Nb3Sn layer formation. In this study, specific diffusion couples
    of Nb/Cu/Sn were fabricated with different combinations of Ti and Zn doping to
    Cu and Sn and their diffusion reaction behaviors in Nb3Sn layer formation were
    investigated. Besides, anticipating a potential grain refinement effect, an Mg
    and Zn co-doped sample was additionally fabricated and the effect of Mg addition
    was compared.
