Cryogenic instrumentation

For the period June 15, 1969 through December 14, 1974, research on Cryogenic Instrumentation was carried out at the University of Virginia as part of project Themis. The emphasis of the program was on experimental and theoretical study of various low temperature phenomena that have device applications, particularly superconducting devices and materials. Accomplishments are reported on the following topics: Tunneling, Conduction and Magnetic Phenomena, Superconductivity in Transition Metals and Transition Metal Compounds, Device Applications of Weak Links, Fluxoid Quantization and Flux Flow, Fundamental Fluctuation Measurements in Superconductor Microchannels, Applications of High Q Superconducting Cavities, Properties of Liquid Helium, and Low Temperature Centrifugation. Short summaries of the work are given together with lists of publications which report the details.
