PROBLEM TO BE SOLVED: To provide a practical oxide superconductive magnet with improved characteristics and sustained reliability. SOLUTION: One side plate 3a is provided with a gas injection port 4, communicating with which a gas reservoir 5a is provided. The other side plate 3b is provided with a gas reservoir 5b that is connected with an exhaust tube 8 having a safety valve 7 and an exhaust air flow regulator valve 6. A winding core 2 between the side plates 3a and 3b is provided with a gas reservoir 5c, and flow pass holes 9a and 9b connect the gas injection port 4 at the side plate 3a and the gas reservoir 5b at the side plate 3b, which communicate with the exhaust tube 8 via a flow pass hole 9c to form a gas flow pass route. Flow pass holes 9n are provided at the gas reservoirs 5a, 5b and 5c, and the exhaust air flow regulator valve 6 is adjusted to cool down an oxide superconductive body 11. COPYRIGHT: (C)2003,JPO |
