Study of the Configuration of the Superconducting Magnet to Reduce Magnetic Field Leakage

Nobuo TERAUCHI, Takashi SASAKAWA


  The inherently stable electrodynamic support system (EDS) used with Superconductive magnets takes the levitation, guidance and propulsion force from the powerful reciprocal action between on-board superconductive coils (SC coils) and ground coils. So it is one of the most important problems to reduce the leakage magnetic flux generated by the SC coils. This report deals with a configuration of the superconducting magnet (SCM) to reduce the weight of magnetic shielding material. This is a way of SCM configuration to reduce the weight of magnetic shielding with small size SC coils at the ends of the SCM. This report examines an SCM configuration designed from the viewpoint of magnetic shielding and the magnetic flux density distribution in the passenger room.
