Cryostat |
| abstract |
The purpose of the present invention is to reduce vibration derived from a refrigeration machine. A cryostat comprises: a helium tank ( 2 ) which stores liquid helium; a refrigeration machine ( 5 ) which is provided above the helium tank ( 2 ) and re-liquefies the vaporized liquid helium in the helium tank ( 2 ); a cylindrical member ( 15 ) which houses the lower part of the refrigeration machine ( 5 ) and forms a liquefaction chamber ( 8 ) communicating with the helium tank ( 2 ); and a buffer tank ( 10 ) which stores helium gas and communicates with at least either the space above the surface of the liquid helium in the helium tank ( 2 ) or the liquefaction chamber ( 8 ). The gas-phase volumes of the helium tank ( 2 ) and the liquefaction chamber ( 8 ) increase by having the buffer tank ( 10 ) communicate with the helium tank ( 2 ) and the liquefaction chamber ( 8 ). |
