Superconducting acceleration cavity, for a charged particle accelerator, is internally polished by chemical polishing and then electrolytic polishing

摘要

Polishing of a superconducting acceleration cavity, by chemical polishing and then electrolytic polishing, is new. Polishing of a superconducting acceleration cavity, formed in an open-ended hollow metal body having a niobium-containing inner metallic surface, is carried out by chemical polishing followed by electrolytic polishing.
