It is attached to the cryogenic refrigerant container by welding, etc. On the other hand, 2 is an inner tube having a flange 2a at its upper end and made of, for example, GFRP with low thermal conductivity, and is disposed inside the outer tube 1 with a certain gap as shown in the figure. Further, this inner tube 2 has a plurality of holes 2b for releasing liquid helium evaporative gas along the nine circumferential directions at the illustrated position on the upper end side, and the holes 2b for releasing liquid helium evaporative gas

でいる。A plurality of (two in this example) current supply conductors 3 are wound in a spiral along the inner tube 2 so as to be longer than the length of the inner tube 2. Roughly speaking, the lead terminal 4 under the Tsunetaki ring block was connected to these two current supply conductors 3, and the excitation N8! was placed in a normal temperature environment. A current is supplied from the lead terminal 4 to a superconducting coil of a superconducting magnet (not shown). As described above, the evaporated liquid helium is released into the atmosphere through the gap between the outer tube 1 and the inner tube 2 through the cryogenic refrigerant evaporated gas release hole 2b and inside the inner tube 2. With this configuration, each current supply conductor 3 is cooled. In addition,
As the material for the above-described current supply conductor 3, for example, copper (phosphorus-deoxidized copper) having low thermal conductivity is used. In addition, from the lower end of the inner tube 2 to the hole 2b for releasing cryogenic refrigerant evaporative gas,
In order to prevent liquid helium gas from entering the pipe, for example, foamed polystyrene is packed as a filler 5 inside the pipe.

給用導体に最適な限界設計を行なうことが可能となる。In the gas cooling current supply lead having such a configuration, since the plurality of current supply conductors 3 are commonly arranged in a single gas cooling pipe consisting of the outer tube 1 and the inner tube 2, the gas cooling current supply lead is The total cross-sectional area of the lead becomes significantly smaller,
As a result, it becomes possible to significantly reduce the amount of heat entering the cryogenic refrigerant container. In addition, since the plurality of current supply conductors 3 are commonly arranged in a single gas flow path formed by the gap between the outer tube 1 and the inner tube 2, the current supply conductors 3 are arranged in common in a single gas flow path formed by the gap between the outer tube 1 and the inner tube 2. The evaporated liquid helium cools each current supply conductor 3 uniformly without causing flow imbalance, thereby increasing cooling efficiency. This results in
It becomes possible to perform optimal limit design for each current supply conductor, such as selection of lead cross section and design of gas cooling pipe.

設置が極めて容易となる。Roughly speaking, in order to reduce the amount of heat intrusion into the cryogenic refrigerant container, even if the length of the current supply conductor 3 is long, the length of the gas cooling pipe consisting of the outer tube 1 and the inner tube 2 is short. This not only makes the structure of the gas-cooled current supply lead extremely compact and compact, but also makes the gas flow path wider and shorter. There will no longer be any road blockages. In addition, even if there are multiple current supply conductors 3, only one gas cooling pipe is required, so less space is required on the top of the cryogenic container, and piping for recovering or discharging liquid helium is also required. Since only one system is required, installation of gas cooling current supply leads is extremely easy.
