Measurement of the high-field Q drop in a high-purity large-grain niobium cavity for different oxidation processes
The most challenging issue for understanding the performance of superconducting radio-frequency (rf) cavities made of high-purity (residual resistivity ratio >200) niobium is due to a sharp degradation (“Q-drop”) of the cavity quality factor Q_{0}(B_{p}) as the peak surface magnetic field (B_{p})...
