RF Superconductivity and Temperature-Mapping at Cornell

A brief review is given on the current research in superconducting RF at Cornell University, with an emphasis on resistive thermometry of cavity surfaces.  The mapping of the temperature rise on the exterior of a X-band single-cell superconducting cavity provides information on the nature of anomalous dissipative losses and aids in identifying defects which ultimately limit the maximum cavity field level.  A new system built at Cornell for temperature-mapping multi-cell cavities will be shown.
