The project developed thin film high temperature superconductors (HTS) on high permittivity substrates. Yttrium boron carbon oxide (YBCO) and bismuth calcium copper oxide (BiSCCO) were deposited by laser ablation, molecular beam epitaxy and radio frequency (rf) sputtering to establish which yields the best large area, single phase, high critical current films. Electrical, physical and chemical properties of films were measured. Microwave components were also made and evaluated. The capability to produce HTS microwave devices starting from powder and deposition of YBCO films to the demonstration of HTS microwave components in properly engineered cryogenic housings was shown. The project produced several adequately operating demonstrators. Other powders and targets were assessed and other films deposited. Production failure risk is much reduced since the project paved way to further development of industrial prototypes. Exploitation for HTS microwave technology depends on development (rather than research) of components, sub-systems and cryogenic engineering developments. If real benefits are to be realised through application of HTS, the advantages have to outweigh the extra complications of employing cryogenic temperatures.
