広い側部通路（７）を素通りしてしまう。(Problems to be Solved by the Invention) In the conventional superconducting coil having the above configuration, when a refrigerant such as liquid helium is supplied from the inlet (6) and recovered from the outlet (9) as shown by the arrow in the figure, Most of the refrigerant passes through the wide side passage (7).

断してある。(Example) Hereinafter, an example of the present invention will be described with reference to FIG. FIG. 1, like FIG. 3, shows a partial cross-sectional view of a superconducting coil. The insulating member (4b) is provided with a plurality of liquid reservoirs (10) which are grooves. The reservoir (10) is connected to the inlet (6) and the internal passageway (8), but is isolated from the outlet (9).

口（９）に向かう。すなわち、入口（６）より供給した
冷媒は必ず内部通路（８）を通る。Since the refrigerant that has flowed into the liquid reservoir (10) cannot flow directly to the outlet (9), it heads to the outlet (9) via the internal passage (8). That is, the refrigerant supplied from the inlet (6) always passes through the internal passage (8).
以上説明したように冷媒は必ず内部通路（８）を通るこ

Regarding the liquid reservoir (10), the part near the inlet (6) is made wide, and the part near the outlet (9) is made narrow. With this configuration, the inner passageway (8) is closer to the vicinity of the inlet (6) and the vicinity of the outlet (9) of the liquid reservoir (10).

媒を強制循環させるか熱対流させる。Note that in order to supply the refrigerant from the inlet (6) and flow it outside the space (2) (not shown) from the outlet (9), the refrigerant is forced to circulate or undergo thermal convection.

きる。In the superconducting coil of the present invention, since the flow rate of refrigerant in the passage (internal passage) between adjacent superconducting wires is increased,
Even if refrigerant bubbles occur in the internal passage, the bubbles tend to move together with the refrigerant. Therefore, cooling of a certain part of the superconducting wire is not obstructed by air bubbles for a long time. Since the cooling performance is thus stabilized, the superconducting state can be stably maintained.
