    摘要： A precursor for a Nb3Sn superconductor wire to be manufactured by the internal diffusion method. The precursor includes Nb-based single core wires, Sn-based single core wires, and a cylindrical diffusion barrier made of Ta or Nb. Each Nb-based single core wire includes a Nb-based core coated with a Cu-based coating made of a Cu-based matrix. Each Sn-based single core wire includes a Sn-based core coated with a Cu-based coating made of a Cu-based matrix. The Nb-based single core wires and the Sn-based single core wires are regularly disposed in the diffusion barrier. The Nb-based single core wires includes at least two kinds of Nb-based single core wires having different Cu/Nb ratios and the Cu/Nb ratio is a cross sectional area ratio of the Cu-based coating to the Nb-based core.

    摘要： An MRI apparatus having a configuration that reduces vibration of a static magnetic field generating source is provided. A closed vessel 2 of the static magnetic field generating source is provided with a rigid structure 4 for preventing transmission of vibration generated from a gradient magnetic field generating part 21 to other members via the closed vessel 2. The rigid structure 4 uses, for example, a connecting part 4 that connects a face 25 on the imaging space side and a face 26 confronting it. The rigidity of the closed vessel is thereby increased, and therefore vibration transmitted from the gradient magnetic field generating part can be reduced. The connecting part can have a through-hole structure, and in such a case, internal space of through-hole can be used for drawing cables.
