In a conventional vacuum‐jacketed cryogen transfer line, the major heat transfer is dominated by two modes: i) radiation between the warm outer pipe and the cold inner pipe and ii) thermal conduction through support members and penetrations. Magnetic levitation makes it possible to eliminate the conduction portion by use of non‐contact support, consisting of high temperature superconductor (HTS) and permanent magnet (PM). Several transfer line prototypes (including a 6‐meter prototype) have been designed and constructed to optimized the levitation and thermal performance. This paper reviews the key design/fabrication issues, such as levitation configuration, levitation force measurement, warm‐support design using smart materials, fabrication process, and technical milestones throughout a 3‐year period. This novel transfer line offers the potential of significant savings of cryogens and hence reduces the cost of crygon use.
