Aging of the HF−H2SO4 electrolyte used for the electropolishing of niobium superconducting radio frequency cavities: Origins and cure

Electropolishing (EP) in the HF−H2SO4 electrolyte is the most desirable surface treatment for niobium superconducting radio frequency cavities yet demonstrated, in terms of performance and surface finish. However, the efficiency of the electrolyte declines quickly with time (decrease in removal rate...
