Fundamentals of Superconductivity
This course on the science and technology of superconductivity comes at a most appropriate time in the over-all development of the field. The late 1950’s and this past decade of the 1960’s were in many ways the golden age of superconductivity. During that period of some fifteen years, superconductivity grew from little more than a laboratory curiosity being studied at a few low temperature centers, to a full fledged science and technology, being actively pursued by scores of industrial and academic laboratories throughout the world. The years between 1959 and 1962 saw a remarkable growth in the superconducting literature. Figure I shows that in 1959 superconducting publications represented some 6% of all low temperature publications. Three years Later in 1962 it represented almost 17% of the total low temperature literature. This present decade is seeing a new and interesting development — the transformation of superconductivity research out of the laboratory into the realm of military and industrial practicality. Some applications are ripe for immediate practical development, others are still in the realm of basic and applied research. In their totality, they represent an impressive list of existing and potential applications. They include: magnets, motors, generators, magnetometers, infrared and millimeter wave detectors, gravity meters, gyroscopes, bolometers, nuclear particle detectors, voltmeters, ammeters, power transmission lines, dc transformers, computer elements, switches, passenger train suspension systems, accelerometers, antennas, amplifiers, microwave cavities, linear accelerators... This list is by no means complete. It continues to grow with the passage of time.
