| Publication Abstract: | A BCP-treated single cell niobium cavity was coated with Nb3Sn following a typical tin vapor diffusion technique. After RF testing with thermometry mapping system, it was dissected to make several cutout samples for the examination of Nb3Sn coated inner surfaces using different surface science techniques. While uniform distribution of coating was observed throughout the surface, some patchy areas containing irregular grains with thinner coating and microscopic pits were found. Using thermometry data measured during the RF test, microstructure and composition of the coating are correlated to the RF surface resistance of the respective areas. |
