Web3Sn films are investigated. The Nb 3Sn phase is obtained by electrodeposition of Sn layers and Cu intermediate layers onto Nb substrates followed by high temperature diffusion in inert atmosphere. Electrodeposition was performed from aqueous solutions at current densities in the 20–50mAcm−2range and at temperatures between 40°C and 50°C. WebSurface Analysis Studies of Nb3Sn Thin Films: 2316 : D.L. Hall, J.J. Kaufman, ... USA : A recent study to optimise the coating of thin-film Nb3Sn cavities has resulted in coating procedures that can fabricate 1.3 GHz cavities capable of reproducibly achieving fields of >16 MV/m with record high Qs >10 10 at 4.2 K. However, the performance of ...
