A superconducting coil device according to one embodiment of the present invention includes: A superconducting coil device including: a bobbin having a tubular body; superconducting wires, a part of which constitutes a wound portion where the superconducting wires are wound on the bobbin; a bobbin-side guide portion holding the superconducting wires extending from the bobbin, the bobbin-side guide portion being provided to extend in a bobbin axial direction, which is an axial direction of the body of the bobbin; a first guide portion holding the superconducting wires extending from the bobbin-side guide portion, the first guide portion being arranged on an outer side of the bobbin-side guide portion in a direction intersecting the bobbin axial direction and provided to extend in the direction intersecting the bobbin axial direction; and a second guide portion capable of holding the superconducting wires extending from the first guide portion, the second guide portion being provided to extend in a direction intersecting the direction of extension of the first guide portion, in which the superconducting wires are constituted of a plurality of wires connected in series, and a connection portion between the wires is fixed to at least either one of the first guide portion and the second guide portion.

Superconducting coil device

The present invention is such that a main body neither drops out nor is destroyed. A plurality of brackets (), provided on a side surface of a main body () in which a superconducting magnet is mounted internally in a state in which each protrudes therefrom, are each supported by a stand () from the bottom, and enclosing members () are attached to the side surface of the main body () with a prescribed space (a) opened from the bottom of the brackets (). At least part of the inside surface of an enclosing member () surrounds a stand () in a non-contact state.

Superconducting magnet apparatus

A superconducting magnet circuit includes, besides a closed circuit formed of a plurality of unit superconducting coils and connected in series and a first persistent-current switch a second persistent-current switch which forms a closed circuit by connecting the ends of an arbitrary unit superconducting coil and is therefore made up of the two closed circuits, whereby their mutual induction suppresses the decay of the magnet apparatus' central magnetic field to provide extreme stability.
