Theory of Nb-Zr Alloy Superconductivity and First Experimental Demonstration for Superconducting Radio-Frequency Cavity Applications
Nathan S. Sitaraman, Zeming Sun, Ben Francis +8
Niobium-zirconium (Nb-Zr) alloy is an old superconductor that is a promising new candidate for superconducting radio-frequency (SRF) cavity applications. Using density-functional a…

Dissipation by surface states in superconducting RF cavities
Sean Deyo, Michelle Kelley, Nathan Sitaraman +5
Recent experiments on superconducting cavities have found that under large radio-frequency (RF) electromagnetic fields the quality factor can improve with increasing field amplitud…
