Abstract : The major problem accomplishments that should be highlighted and summarized in this final report are the following: (1) An extensive and complete analysis of the modes of operation, circuit optimization and sensitivity limits of the rf biased SQUID was completed; (2) Advanced state-of-the-art microfabrication techniques were developed and applied to the production and study of superconducting thin film microbridges, with concentration on submicron superconductor-normal metal-superconductor junctions; and (3) A new reactive ion beam oxidation procedure was developed and applied, with the aid of micro-lithography techniques to the production of very high quality, niobium-niobium oxide tunnel junctions with submicron dimensions.
