Description
This work reports the first application of centrifugal barrel polishing (CBP) to a 650 MHz single-cell niobium superconducting radio frequency cavity. The CBP was performed using a newly installed large tumbler designed to accommodate four large-sized 650 MHz multi-cell cavities. The CBP process was applied to reset the cavity’s internal rough surface prior to electropolishing (EP). The study presents results on the surface condition and SRF performance following the CBP and subsequent standard cavity surface processing.
