THE HIGH-TEMPERATURE SUPERCONDUCTIVITY SPACE EXPERIMENT (HTSSE)

The High Temperature Superconductivity Space Experiment (HTSSE) progra m, initiated by the Naval Research Laboratory (NRL) in 1988, is descri bed. The HTSSE program focuses high temperature superconductor (HTS) t echnology applications on space systems. The program phases, goals and objectives are discussed. The devices developed for this program and their suppliers are enumerated. For HTSSE-I, 15 space-qualified, passi ve microwave devices were integrated onto a cryogenic cold bus as an e xperimental payload on a DoD spacecraft. The experiment payload and sc ientific data measurement systems, designed, developed, and built by N RL, are described.
