Description
Zr-Nb alloys are a promising candidate for SRF cavities due to their reduced sensitivity to stoichiometric deviations, intrinsically smoother interfaces rising from their continuous phase with niobium, and large estimated coherence length. We present surface characterization of this material, introduce a method to coat SRF cavities with this alloy that overcomes the electrochemical instability of zirconium, and report early RF performance results to demonstrate the feasibility of this alloy for SRF applications.
