Superconducting magnet and regenerative refrigerator for the magnet |
摘要 |
Superconducting magnet and regenerative refrigerator can be reduced in size of the apparatus and is capable of reducing the evaporating amount of liquid helium. A coil portion second thermal shield 17a and a coil portion thermal shield 8a are disposed so as to enclose a coil portion helium tank 2a which contains superconducting coil 1. Further, a helium portion second thermal shield 17b and a helium reservoir portion thermal shield 8b are disposed so as to enclose a helium reservoir tank 2b which stores liquid helium 3. A coil portion second thermal shield 17a and a coil portion thermal shield 8a are cooled by a coil portion 2-stage type Gifford-McMahon cycle refrigerator 50a while a helium portion second thermal shield 17b and a helium reservoir portion thermal shield 8b are cooled by a helium reservoir portion 2-stage type Gifford-McMahon cycle refrigerator 50b.
