摘要：

Melt-processed YBa2Cu3Ox thick film components for resonant cavities have been produced on yttria stabilized zirconica substrates. A variety of cavities have been constructed incorporating both copper and superconducting components and the TE011 modes have been examined. The highest unloaded Q factor measured was 715 688 for the TE011 mode of an all superconducting cavity at 77 K and 5.66 GHz in the Earth's magnetic field. This corresponds to a surface resistance of 1.09 m-OMEGA over a total surface area in excess of 230 cm2. Cooling this cavity within a mumetal shield increased the unloaded Q factor by approximately 5%.
