| Abstract: |
| Current leads are required in superconducting devices to connect the external power supply at room temperature to the superconducting magnet in cryostats. The total heat loss could be effectively reduced by applying high temperature superconducting current leads (HTS-CL), and the operation cost could be lightened. The optimization goal of HTS-CL is to reduce the total heat loss of current leads while extend its loss of flow accident (LOFA) time and burnout time based on the designed current.This paper summarized the heat transfer analysis, structure design, safety evaluation and the application cases of HTS-CL. |
