Confirmation of the durability of superconducting magnets and ground coils

To obtain some idea of maintenance periodicity, the RTRI is promoting endurance confirmation tests on superconducting magnets and ground coils.

Development of PLG coil

The RTRI is promoting the development of a PLG coil to replace the three separate coils used for propulsion, levitation and guidance. This is expected to significantly cut the construction costs of the Maglev system.

Development of a bulk high-temperature superconducting conductor

The RTRI has succeeded in capturing a magnetic field greater than 17 tesla in the development of a bulk high-temperature superconducting conductor using yttrium-based materials. Research and development for its application is now underway.
