    "abstract": "The proposed linear electron-positron collider TESLA is based on 1.3 GHz\nsuperconducting niobium cavities for particle acceleration. For a\ncentre-of-mass energy of 500 GeV, an accelerating field of 23.4 MV/m is\nrequired which is reliably achieved with a niobium surface preparation by\nchemical etching. An upgrade of the collider to 800 GeV requires an improved\ncavity preparation technique. In this paper, results are presented on\nsingle-cell cavities which demonstrate that fields of up to 40 MV/m are\naccessible by electrolytic polishing of the inner surface of the cavity.",
