Abstract
A superconducting temperature controller that can sense the temperature of an area and also heat the enclosed area. A superconducting thin film resistor mounted on a substrate is disposed in an enclosed housing that forms a vacuum. Also disposed within the housing is a heat sink that keeps the temperature inside the housing below the transition temperature of the superconducting material that forms the thin film resistor. By applying a constant voltage to the thin film resistor, the temperature of the substrate and thin film resistor can be maintained at a predetermined level that is within the transition temperature region of the superconducting material being used.
