Abstract
Systems and methods for regulating, for example, the temperature of high temperature superconducting (HTSC) thin film filters. A multi-stage temperature controller comprises a first loop and a second loop. The first loop is used to regulate the cold finger temperature of, for example, a Stirling cycle cryocooler, and the second loop is used to set a reference for the first loop based upon a comparison between a reference signal and a signal received from a cold stage temperature sensor. A filter loop also may be used to regulate the temperature of independent HTSC thin film filter carrier packages.
