<p><P>PROBLEM TO BE SOLVED: To improve cooling efficiency in a superconducting coil without increasing a cost concerning a superconducting magnet device unit having a cooling means for cooling the superconducting coil. <P>SOLUTION: The superconducting magnet device unit includes a superconducting magnet device 10 and a heat absorber 20. The superconducting magnet device 10 includes: the superconducting coil 13; a freezing machine 18 for performing cooling to allow the superconducting coil 13 to be in a superconducting state; and load support bodies 15, 16 for supporting the superconducting coil 13. The heat absorber 20 includes: a heat absorption tank 21 for storing liquid helium; a heat-transfer member 22A for thermally connecting the heat absorption tank 21 to the superconducting coil 13; and a heat switch 23 for turning on/off the thermal connection between the heat absorption tank 21 and the superconducting coil 13. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
