Abstract :
An HTS magnet for a Superconducting Maglev, consisting of four persistent current HTS coils, was developed. The HTS coils are installed in a cryostat, and cooled to approximately 15 K by conduction cooling, using two sets of two-stage GM type pulse tube cryocoolers. The HTS magnet is operated in a persistent current mode at a rated magneto-motive force of 750 kA. The running tests were executed on the Yamanashi Maglev Test Line, with a top speed of 553 km/h achieved on December 2, 2005. The test result demonstrated that the HTS coils generated no excessive vibration or heat load.
