Double pancake coil positioning member, superconducting electromagnet apparatus manufacturing method, and superconducting electromagnet apparatus

摘要

This superconductive magnet device is provided with: a vacuum vessel; a coil body accommodated in this vacuum vessel and constituted by laminating a plurality of double pancake coils; and a double pancake coil positioning member provided on an inside circle side of the coil body. This double pancake coil positioning member has a plurality of channels extending in the circumferential direction formed on the outer peripheral surface thereof at intervals along the direction of an axial line for the coil, and a protruding part of an insulating spacer is fitted into each of these channels.
