Microprocessing of superconducting Nb3Sn tapes by electron-beam microetching

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The unsuitable mechanical properties of Nb3Sn (its brittleness) make the production of a conductor in the required shape and dimensions very difficult. A method has been proposed and experimentally investigated by which the existing superconducting Nb3Sn tape could be modified to obtain intrinsically stable superconductor. The required filamentation of commercial Nb3Sn conductor is manageable by electron-beam microetching. The achieved results could serve as a starting point for the construction of a special electron-beam machine. Such device may work in connection with the Nb3Sn producing apparatus.
