| Abstract | Niobium-3 tin Nb3Sn is a promising material for next-generation superconducting RF cavities due to its high critical temperature and high theoretical field limit. There is currently significant worldwide effort aiming to improve Nb3Sn growth to push this material to its ultimate performance limits. In this paper, we present the first results of deposition of Sn on different Nb samples in different orientations in our Chemical Vapor Deposition (CVD) system. We discuss imaging results for Sn on Nb substrates. We discuss CFD flow simulations and how they may be relevant to formulating a recipe for coating cavities. We describe the parameters used in the film deposition and future steps towards coating a 2.6 GHz cavity in our CVD system. We also discuss potential alternative tin precursors to improve coating uniformity and stoichiometry. |
