Description
The performance of Nb3Sn as the next-generation material for SRF cavities is limited by the ability to achieve uniform, dense nucleation during the vapor diffusion growth process. In this work, we study how the Nb surface oxide evolves under UHV annealing, following the temperature profile used in Nb3Sn vapor diffusion growth. By comparing native and anodized oxide surfaces, we investigate how the different surface chemistries and morphologies influence nucleation, providing insight into strategies for improving Nb3Sn film quality and SRF cavity performance.
